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.
Our Lord said we will know people by their fruit. Another way of saying that is, “Look at the evidence,” or “Pay attention to the outcome of any one action.” Since we are governed by the law of reaping and sowing, or you could say cause and effect, we can rest assured that we can learn right from wrong. We can also trust that all and only good comes from the Father. Though spiritual maturity doesn’t happen overnight, we can still rest assured that if we ask for spiritual growth, or for the fruit of the Holy Spirit, it will be given; if we seek, we will find; if we knock, it shall be opened unto us: For every one that asks receives; and he that seeks finds; and to him that knocks the door will be opened (Matt. 7:7-8). It’s not like a fairy godmother gift, it is putting on the mind of Christ and being transformed by the way we think. It’s a lifetime of growing up.
