Is there ever a point in our lives where we outgrow our need for sanctification?
Carlton McLeod explains in this video that as Christians, we are not perfect and we never will be. Even when we think that we are at a good spot and "have it all together," we should always be reforming and we must remain teachable. We must realize there are degrees of knowledge that we have not attained to.
We cannot let pride deceive us into thinking that we can somehow reach a point in our life where repentance and sanctification are not needed. We must be people who embrace humility and are willing to take correction and to repent of sin where need be.
2 Peter 3:17-18 (NKJV) - "You therefore, beloved, since you know this beforehand, beware lest you also fall from your own steadfastness, being led away with the error of the wicked; but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and forever. Amen."
