Some believers find it difficult to understand that since they are “complete in Him” (Colossians 2:9-10), then how can they possibly “grow in Christ”. At the other end of the spectrum we have believers who want God to make them better than they are. In one group I was in we sang a hymn, one line of which went “Lord, plant my feet on higher ground.” I now know He is not going to pick up my feet and plant them higher, for He has already provided for my growth.

There are three verses in the epistles that use the word “grow”. We have the well-known exhortation “Like newborn infants, long for the pure spiritual milk, that by it you may grow up into salvation” (I Peter 2:2 ESV). Then we read, “But grow in the grace and knowledge of our Lord and Savior Jesus Christ” (II Peter 3:18). Both of these statement were written to born-again Jews who were dispersed among other nations.

The major passage is from Ephesians, considered by some to be the highest revelation of God to man. “Rather, speaking the truth in love, we are to grow up in every way into him who is the head, into Christ” (Ephesians 4:15). The context speaks of attaining “mature manhood, to the measure of the stature of the fullness of Christ” (verse 13). The phrase we need to focus on is “grow up… into him… into Christ.”

We are to grow from “children” (verse 14) to “manhood” (verse 13), and all this is “in Christ”. Immediately the illustration of I John comes to mind — “little children”, “young men”, and “fathers” (I John 2:12-14). It is generally agreed that fathers are “those mature believers with long and rich experience” (Robertson’s Word Pictures).

A seed is perfect but God designed it to grow. The seed of eternal life in you is also designed to grow. So, yes, all believers are complete in Him, yet as we read and read again that part of God’s Word addressed to us (from Romans to Philemon), our relationship with the Christ within and our loving Father grows and grows until we reach “the stature of the fullness of Christ”, also referred to as “mature manhood”. It is not talking about position but relationship.
