it's kind of kind to understand the concept of trinity, and different people might give different illustrations. 2 of the illustrations that i use the most would be:
illus 1:
think of a cup of milk coffee. a milk coffee is only a milk coffee when there is black coffee, sugar/creamer and milk, they are 3 but yet known as 1, milk coffee. it's not a complete picture, but it can be absorbed easily by many people who first come across this trinity issue.
illus 2:
think of your father. your father is a father, at the same time, he is a man, and he is also a husband. this illustration is also pretty simple and straight forward.
if i remembered correctly, there is one question posed mentioning that "your God is weaker than a bunch of jews". to reply this, there are many point, but the host didn't even mention 1 of them.

(by the way, after some googling, seems like the video is made by anti-christians and the channel does not really exists) alright, some answers

Jesus died in the form of a man. Jesus was a man in nature, but a God in identity. there for the man can die, but the identity of God remains. this is not going to be easily explained... i give up explaining this through online forum.

. apart from that, Jesus' crucifixion is part of God's plan. an animal need to be sacrificed so that the sin of man can be put on to the animal and the animal die in place of the human. it's also similar to Muslims, Hari Raya Korban. to carry the sins for all, a pure spotless being is needed. therefore Jesus came.
I posted this somewhere ... hope it is helpful for you:
God is uniquely one yet threeFirst Corinthians 8:4: "There is no God but one."
Isaiah 45:5: "I am Jehovah and there is no one else;/Besides Me there is no God." In verses 6, 21, and 22; 46:9; and 44:6, 8, we also find the same words.
Psalm 86:10: "Thou art God alone."
Although there is only one God, the Bible also reveals that this one God is plural, that He has the aspect of three. Genesis 1:1 says that in the beginning God created the heavens and the earth. The Hebrew word for God in this verse is Elohim, which is plural in number.
Genesis 1:26 records that God said, “Let us make man in our image, after our likeness.” The words us and our show that the one God has a plural aspect. In Isaiah 6:8 God said, “Whom shall I send, and who will go for us?” In this verse I is us, and us is I. These verses shows us that God is not merely singular or merely plural. The God revealed in the Bible is “uni-plural.”
In Matthew 28:19 the Lord Jesus charged the disciples to baptize people into the name (singular) of the Father, of the Son, and of the Holy Spirit. C. I. Scofield says in a note to this verse in his reference Bible: “The word is in the singular, the `name,’ not names. Father, Son, and Holy Spirit is the final name of the one true God.”
The Eternal Coexistence and Coinherence of the Divine TrinityIsaiah 9:6 says, "Unto us a child is born, unto us a son is given...and his name shall be called...Mighty God, Everlasting Father." In this verse, the "Mighty God" matches the "child," and "Everlasting Father" matches the "son." Yes, He is a child, yet He is the Mighty God. The child who was born in the manger in Bethlehem was the Mighty God.
John 14:7-11 says, "If ye had known me, ye would have known my Father also: from henceforth ye know him, and have seen him. Philip saith unto him, Lord, show us the Father, and it sufficeth us. Jesus saith unto him, Have I been so long time with you, and dost thou not know me, Philip? he that hath seen me hath seen the Father; how sayest thou, Show us the Father? Believest thou not that I am in the Father, and the Father in me? the words that I say unto you I speak not from myself: but the Father abiding in me doeth his works. Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake." In these verses the Lord clearly reveals to us the mystery that He and the Father are one; He is in the Father and the Father is in Him; when He speaks, it is the Father who works; when men see Him, they see the Father; when they know Him, they know the Father, because He is the Father; He "and the Father are one" (John 10:30).
Second Corinthians 3:17 says, "The Lord is the Spirit." The "Lord" spoken of here, of course, is the Lord Jesus; and "the Spirit," of course, is the Holy Spirit.
The Father is God. Eph 1:17, 4:6, 1 Cor 1:3
Son is God. Heb 1:8, Romans 9:5, John 1:1,14
Spirit is God. In Acts 5 Peter told Ananias that he had lied to the Holy Spirit (v. 3). Then he said, “You have not lied to men but to God” (v. 4).I guess there is just too many references to list here. Hope it helps.
The Father Is Eternal. Isa. 9:6;
The Son Is Eternal. Heb. 7:3;
The Spirit Is Eternal. Heb. 9:14All Three of the Trinity are eternal. The Father, Son, and Spirit do not exist in three temporary, successive modes or stages. According to Isaiah 9:6, the Father is the eternal Father. Additionally, the Son, as the real Melchisedec in Hebrews 7:3, has “neither beginning of days nor end of life.” He is our High Priest perpetually. He is forever the same, and His years will not fail (Heb. 1:12). Finally, it was through the eternal Spirit that Christ offered Himself on the cross without blemish to God (Heb. 9:14).
The Father, the Son, and the Spirit Coexist and Coinhere. John 14:26; 15:26That the Three of the Godhead are eternal implies that They coexist from eternity past through eternity future. Many verses demonstrate the coexistence among the Three of the Triune God. In one of the most graphic, Matthew’s account of Christ’s baptism, as Jesus the Son went up from the water, the Spirit of God descended upon Him as a dove and the Father testified from the heavens of His beloved Son (3:16-17). This scene clearly portrays the simultaneous existence of the Father, the Son, and the Spirit. Further, in John 14:16-17 the Son promised to ask the Father to send the Spirit of reality as the second Comforter; the Father answered the Son’s prayer by sending the Spirit (John 14:26).
The Father and the Son Are Inseparable. John 14:10-11; 8:29; 16:32Though the Three are distinct in their eternal coexistence, They are by no means three separate Gods. Rather, They coinhere mutually and inseparably; that is, They indwell one another. Throughout the Gospels, the Lord Jesus took many opportunities to reveal to the disciples His mysterious coinherent relationship with the Father. For example, in John 14:11, the Lord responded to Philip’s desire to see the Father by assuring him of Their intrinsic oneness: “Believe Me that I am in the Father and the Father is in Me.” Thus the Son, while physically on the earth, mystically dwelt in the Father and the Father in the Son. In addition, the Lord declared in John 6:46, “Not that anyone has seen the Father, except Him who is from God, He has seen the Father.” The Greek preposition para, translated “from” in this verse, literally means “from with.” Hence, the Son sent from God was simultaneously sent with God. The Lord testified of this intimate inseparability: “He who sent Me is with Me; He has not left Me alone” (John 8:29).
I finish this post with this:
In order to know the truth concerning the Triune God in a full, complete, and balanced way. We need to see principle of the twofoldness of divine truth. Robert Govett in his booklet, "The Twofoldness of Divine Truth", says
The twofoldness of truth as offered to our view in Holy Writ is one strong argument of its not being the work of man. It is the glory of man’s intellect to produce oneness. His aim is to trace different results to one principle, to clear it of ambiguities, to show how, through varied appearances, one law holds. Anything that stands in the way of the completeness of this, he eludes or denies.
“But,” as Govett continues, “it is not so with God. In nature He is continually acting with two seemingly opposed principles”. Therefore, Govett says, “It is not then to be wondered at, if two seemingly opposed principles are found placed side by side in the Scripture. ‘Unity in plurality, plurality in unity’ is the main principle on which both the world and the Scripture are constructed”.
Recognizing that the truth concerning the Triune God is twofold is a requirement for knowing God in His trinity. This twofoldness of the truth is embodied in the word triune, a Latin word composed of tri-, meaning three, and -une, meaning one. To say that God is triune is to testify that He is three-one. He is uniquely one, yet He is distinctly and inseparably three. In the Godhead the Father, the Son, and the Spirit are distinct but inseparable. In God’s being one there is no separation among the Father, the Son, and the Spirit, and in God’s being three there is a distinction among the Father, the Son, and the Spirit. The three of the Trinity cannot be separated, yet there is a distinction among them. This is the twofoldness of the truth concerning the Triune God.
