To walk by faith is not walking in ignorance. It is being confident that the fruit of the Holy Spirit is the best weapon of warfare against the works of the flesh. We have all come into the world with the natural reaction to reach for the works of the flesh as our weapons against the same. After we are born from above, we struggle to break this bad habit, or reflex, that we inherited through our natural bloodline. Therefore, when we read in Galatians 5:17-32 and familiarize ourselves with the difference between the two natures we can challenge ourselves to reach for the fruit of the Holy Spirit until we are persuaded they really do work. Then we can say we are walking by faith.
