1 Corinthians 13:11-12 (AMP)
11 When I was a child, I talked like a child, I thought like a child, I reasoned like a child; when I became a man, I did away with childish things.
When we come to Christ, we all begin as babies in the faith. Just like babies in the natural, we are limited in what we know and thus we are limited in what we understand and what we can do. As we grow in the faith we begin to gain a deeper understanding our our new identity in Christ. We continue to gain deeper understanding of whom we are and where we are positioned in Him. We also realize and begin to put to use the authority and power we have in him and in so doing we experience life on a whole new level.
True transformation and maturity begin to manifest even for others to see and experience when the fruit of the Spirit begins to manifest in our lives.
Galatians 5:22-23 (AMP)
22 But the fruit of the Spirit [the result of His presence within us] is love [unselfish concern for others], joy, [inner] peace, patience [not the ability to wait, but how we act while waiting], kindness, goodness, faithfulness, 23 gentleness, self-control. Against such things there is no law.
Maturity in Christ is not only about knowing but the manifestation of what we know and believe in our lives. It is to become more like him. The character traits of the old sinful man die off and a new character, the character of Christ is manifested in my daily life. Now that’s a man or woman rooted in sound doctrine and maturing in Christ.
God makes as sound and mature as we remain obedient to his word and as we set our mind on the things of the spirit and not the flesh. Our focus has to change for us to grow and mature. As someone said, what you feed grows and what you starve dies off. When we lack this focus and commitment then we end up like the believers in Hebrews
Hebrews 5:12 (AMP)
12 For though by this time you ought to be teachers [because of the time you have had to learn these truths], you actually need someone to teach you again the elementary principles of God’s word [from the beginning], and you have come to be continually in need of milk, not solid food.
Are you being transformed into a mature man/woman in Christ or have you deliberately refused to grow and be transformed such that you are always crying out for milk and not solid food though you have been a believer for quite some time? Is the transformation evident for others to see?
