English preacher F. B. Meyer (1847–1929) used the example of an egg to illustrate what he called “the deep philosophy of the indwelling Christ.” He noted how the fertilized yolk is a little “life germ” that grows more and more each day until the chick is formed in the shell. So too will Jesus come to live with us through His Holy Spirit, changing us. Meyer said, “From now on Christ is going to grow and increase and absorb into Himself everything else, and be formed in you.”
He apologized for stating the truths of Jesus imperfectly, knowing that his words couldn’t fully convey the wonderful reality of Christ dwelling in believers through the Holy Spirit. But he urged his listeners to share with others, however imperfectly, what Jesus meant when He said, “On that day you will realize that I am in my Father, and you are in me, and I am in you” (John 14:20). Jesus said these words on the night of His last supper with His friends. He wanted them to know that He and His Father would come and make their home with those who obey Him (v. 23). This is possible because through the Spirit Jesus dwells in those who believe in Him, changing them from the inside out.
No matter how you picture it, we have Christ living inside us, guiding us and helping us to grow to be more like Him.
