God never promised to remove all trials or to give us heaven on earth. However, He has promised that the man who separates himself from the world and gives himself over to the Lord will be blessed.
God shows through Job that what really matters is how things turn out in the end.
Uzziah was a great king and was greatly blessed of the Lord. At the peak of his strength, he began to trust in himself. His strength led to his fall. It is often in times of perceived strength that saints of God become most vulnerable.
We could truly serve the Lord if we were strong and courageous Christians in all places.
These things describe a middle of the road believer: steps of a good man, delight of a good man, and fall of a good man.
