Of course growing as a Christian involves gaining more knowledge of God’s Word; it implies a life of prayer and witness. But these are all the results of something more basic. Being a Christian means knowing God. Growing as a Christian means increasing in our desire to know God. This is the sum of the Christian life. Jesus himself said: “This is eternal life: that they may know you, the only true God” (John 17:3).
The true men and women of faith are “the people who know their God” (Daniel 11:32). That is why, in the Old Testament, one of the anticipated blessings of the new age which the Messiah would inaugurate was that then men and women would “know the Lord” Jeremiah 31:34). This is the heart of the Christian life. It is fundamental to all spiritual growth. If we are not growing in the knowledge of God, we are not growing at all.
