Birth is only the beginning for a newborn baby; that child isn't meant to be a baby forever, but to grow and become strong and eventually reach adulthood. The same is true for us. When we first come to Christ we are "spiritual newborns"- but we aren't meant to remain that way. God's plan is for us to grow strong in our faith and become mature in our understanding of God's will.
Are you growing in your faith> If not, why not? Make God's " pure spiritual milk " part of your soul's daily diet. And what is that ? His Word!
"Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation." 1 Peter 2:2
