6 Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age, who are doomed to pass away. (1Co 1:28; 1Co 3:1; Php 3:15; Jas 3:15)7 But we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory. (Ro 16:25; Eph 3:5; Eph 3:9; Col 1:26; 2Ti 1:9)8 None of the rulers of this age understood this, for if they had, they would not have crucified the Lord of glory. (Ps 24:7; Lu 24:20; Ac 3:17; Ac 7:2; Ac 13:27; Jas 2:1)9 But, as it is written, “What no eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him”— (Isa 64:4; Mt 25:34; Jas 1:12)10 these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. (Mt 16:17; Joh 14:26; Ga 1:12; Ga 1:16; Eph 3:3; Eph 3:5; Re 2:24)11 For who knows a person’s thoughts except the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God. (Pr 20:27)12 Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God. (Ro 8:15; 1Jo 4:4)13 And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.
