In 2 Corinthians 5:7 Paul tells the church in Corinth that despite all the obstacles they faced in their journey to minister the Gospel they could keep going because they were walking by faith and not by sight.  Walking by sight is the opposite of walking by faith. When we walk by sight we are not pleasing to God.  10 of the 12 spies walked by sight but despite getting ready to be stoned Joshua and Caleb walked by faith.  Peter walked by sight when he sunk after he walked on water.  Christians tend to want to relate to Joshua and Caleb or Peter when he walked on water not recognizing many instead resemble the 10 spies and Peter who sunk in the water.
