Worldly (carnal) Christians –

Spiritual (mature) Christians
What, after all, is Apollos? And what is Paul? Only servants, through whom you came to believe—as the Lord has assigned to each his task. I planted the seed, Apollos watered it, but God made it grow. So neither he who plants nor he who waters is anything, but only God, who makes things grow. The man who plants and the man who waters have one purpose, and each will be rewarded according to his own labor. For we are God's fellow workers; you are God's field, God's building – 1 Corinthians 3:5-9, NIV
“ … so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.
Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of men in their deceitful scheming. Instead, speaking the truth in love, we will in all things grow up into him who is the Head, that is, Christ” – Ephesians 4:12b-15, NIV
Follow my example, as I follow the example of Christ. - 1 Corinthians 11:1, NIV
