Rich in all are as reward but must not be greed.

If a world without problems, we surely wont rely or need god, perhaps we treat ourself as god. Reason for problems occur in your life is the key / test of how we strengthen our faith on God. That's why whenever there are humans, there's problems. Each individual will explore their own problems, and whoever over the problems will be grow in another level. Every problems do carry a message from God for we to learn. If we yet to learn from the problem, although it seems that we did solve it. For sure, the problem will come back to us again till we really learn our lesson which God prepared for us before receiving greater gifts from God. That's why do submit to things to God and ask for guidance.
