1 Corinthians 3:2

3:2 I fed you milk, ¹  not solid food, for you were not yet ready. In fact, you are still not ready,

1 Corinthians 12:31

12:31 But you should be eager for the greater gifts.

And now I will show you a way that is beyond comparison. ² 

1 Corinthians 3:3

3:3 for you are still influenced by the flesh. ³  For since there is still jealousy and dissension among you, are you not influenced by the flesh and behaving like unregenerate people? ⁴ 

1 Corinthians 15:17

15:17 And if Christ has not been raised, your faith is useless; you are still in your sins.

[3:2]  ¹ sn Milk refers figuratively to basic or elementary Christian teaching. Paul’s point was that the Corinthian believers he was writing to here were not mature enough to receive more advanced teaching. This was not a problem at the time, when they were recent converts, but the problem now is that they are still not ready.

[12:31]  ² tn Grk “a still more excellent way.” In this context the phrase has an elative rather than a comparative sense, however.

[3:3]  ³ tn Or “are still merely human”; Grk “fleshly.” Cf. BDAG 914 s.v. σαρκικός 2, “pert. to being human at a disappointing level of behavior or characteristics, (merely) human.” The same phrase occurs again later in this verse.

[3:3]  ⁴ tn Grk “and walking in accordance with man,” i.e., living like (fallen) humanity without the Spirit’s influence; hence, “unregenerate people.”
