How long have you been born again? How long have you been a child of God? Have you grown up in the Lord since then?
And I, brethren, could not speak to you as to spiritual people but as to carnal, as to babes in Christ. I fed you with milk and not with solid food; for until now you were not able to receive it, and even now you are still not able; for you are still carnal. For where there are envy, strife, and divisions among you, are you not carnal and behaving like mere men?—1 Corinthians 3:1-3
As children of God, we are expected to grow up just like newborn babies. It’s acceptable for an infant to wear diapers and do his “business” there, however, it’s totally unacceptable for a teenager to continue wearing diapers (except if sick). In the above passage, Paul is frustrated at the Corinthians who, after about 5 years of receiving Christ, are still behaving like the people of the world by indulging in jealousy, envy, quarrels, sexual immorality, etc.
Are you also found in this same condition that after years of being in Christ, you continue to act as a “mere man”? A new employee is expected to make mistakes here and there but after working for 3, 5, or 10 years in the job, he/she should become experienced; so should it be with children of God.
For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil—Hebrews 5:12-14
Have you ever taught the Word of God to someone or do you rely on your pastor to do it? Are you still defeated by anger, gossip, unforgiveness, worries, or lust for worldly things? It’s not that those who have been born again for a long time should be perfect by now but we should daily “press on to reach the end of the race and receive the heavenly prize for which God, through Christ Jesus, is calling us” Philippians 3:13-14. A racer doesn’t run in the same spot, he moves forward to get closer and closer to his destination. As children of God, we should seek to grow in the Lord: Be constantly filled with the Holy Spirit, overcome our persistent bad habits, submit to God, and resist the devil. We should seek to mature in Christ so that the Father can entrust us with greater revelations about His Word and opportunities to serve Him.
