Now we get to some of the reasons of why we should consider facing trials to be pure joy. We should remember that Paul (Romans 5:3-5) and Peter (1 Peter 1:6-9) said very similar things. So there is no getting away from this lesson!
Testing produces perseverance. Perseverance is a steadfast and unshakable conviction in the truth of what God says. Trials prove that what God says is right. So when we go through trials we will eventually learn that God is even more faithful than we imagined at the outset. We need to let perseverance complete its work in us if we are to be mature.
Trials test our wisdom, because we face situations and we simply do not know what to do. If we find ourselves in such situations we are to ask God. He will give us wisdom, and He does so without finding fault. Emotions common in trials are feelings of inadequacy and unworthiness. So we then deduce that God will not help us because we do not deserve it. This is wrong. He gives without finding fault. He puts us through trials so that He can rectify faults within us, not so that He can condemn us for them.
We need to have faith in God.
