I've learnt that problems that happen in our lives are because God wants to test us, test our faith, that is the point of life, to freely choose to love God and have faith in him and Jesus Christ even amongst the barrage of problems that may be in our way. If we choose to not love God then we are surely lost because he himself is the only one that can help. It is like you are in a forest, sometimes you may get stuck in the mud and feel like you are moving no where in life. The dark dense jungle is our lives, the only way out to a better place is with God. The believer see's a light amongst the dusk of the jungle, the non believer is left in darkness. The believer will see the light and God will shine that light upon him to show him the correct path. But you will never see the light if you don't look for it and don't believe you will see it.
