There is often a vast difference between our expectations and how God arranges for things to turn out. God’s thoughts are higher than our thoughts. His actions differ totally from ours. For this reason, it is impossible for us to explain God’s actions. Unlike us, God can see the future. Often we find that the things that were most difficult to work through were used by God for our own good.
