1 Corinthians 2:6-16 teaches that we talk about wisdom, things not from the spirit of the world but from the spirit that teaches, the Holy Spirit!
In the Christian Greek Scriptures the words te′lei·os, te·lei·o′tes, and te·lei·o′o are used conveying such ideas as bringing to completeness or full measure (Lu 8:14; 2Co 12:9; Jas 1:4), being full grown, adult, or mature (1Co 14:20; Heb 5:14), having attained the appropriate or appointed end, purpose, or goal.
The basic terms signifying wisdom is the Hebrew word chokh·mah′ and the Greek word so·phi′a, with their related forms. The Hebrew word tu·shi·yah′, which may be rendered “effectual working” or “practical wisdom,” and the Greek word phro′ni·mos and phro′ne·sis (from phren, the “mind”), relating to “sensibleness,” “discretion,” or “practical wisdom.” At some point we realize the just more than the born difference of good and bad, but have Jehovah's Gods mental regulation too. We can make better decisions knowing we are pleasing God with his blessings.
NWT of the JW Ephesians 4:2-16
" 2 with complete lowliness of mind and mildness, with long-suffering, putting up with one another in love, 3 earnestly endeavoring to observe the oneness of the spirit in the uniting bond of peace. 4 One body there is, and one spirit, even as YOU were called in the one hope to which YOU were called;5 one Lord, one faith, one baptism; 6 one God and Father of all [persons], who is over all and through all and in all.
7 Now to each one of us undeserved kindness was given according to how the Christ measured out the free gift. 8 Wherefore he says: “When he ascended on high he carried away captives; he gave gifts [in] men.” 9 Now the expression “he ascended,” what does it mean but that he also descended into the lower regions, that is, the earth? 10 The very one that descended is also the one that ascended far above all the heavens, that he might give fullness to all things.
11 And he gave some as apostles, some as prophets, some as evangelizers, some as shepherds and teachers, 12 with a view to the readjustment of the holy ones, for ministerial work, for the building up of the body of the Christ, 13 until we all attain to the oneness in the faith and in the accurate knowledge of the Son of God, to a full-grown man, to the measure of stature that belongs to the fullness of the Christ; 14in order that we should no longer be babes, tossed about as by waves and carried hither and thither by every wind of teaching by means of the trickery of men, by means of cunning in contriving error. 15 But speaking the truth, let us by love grow up in all things into him who is the head, Christ. 16 From him all the body, by being harmoniously joined together and being made to cooperate through every joint that gives what is needed, according to the functioning of each respective member in due measure, makes for the growth of the body for the building up of itself in love."
SearchGodsWord.org KJV Ephesians 4:2-16"
2 With all lowliness and meekness, with longsuffering, forbearing (5740) one another in love; 3 Endeavouring (5723) to keep (5721) the unity of theSpirit in the bond of peace. 4 There is one body, and one Spirit, even as yeare called (5681) in one hope of your calling; 5 One Lord, one faith, onebaptism, 6 One God and Father of all, who is above all, and through all, andin you all. 7 But unto every one of us is given (5681) grace according to themeasure of the gift of Christ. 8 Wherefore he saith (5719), When heascended (5631) up on high, he led captivity (5656) captive, and gave (5656)gifts unto men. 9 (Now that he ascended (5627), what is it (5748) but thathe also descended (5627) first into the lower parts of the earth? 10 He thatdescended (5631) is (5748) the same also that ascended up (5631) far aboveall heavens, that he might fill (5661) all things.) 11 And he gave (5656)some, apostles; and some, prophets; and some, evangelists; and some,pastors and teachers; 12 For the perfecting of the saints, for the work of theministry, for the edifying of the body of Christ: 13 Till we all come (5661)in the unity of the faith, and of the knowledge of the Son of God, unto aperfect man, unto the measure of the stature of the fulness of Christ:14 That we henceforth be (5753) no more children, tossed to and fro(5740), and carried about with (5746) every wind of doctrine, by the sleightof men, and cunning craftiness *, whereby they lie in wait to deceive;15 But speaking the truth (5723) in love, may grow up (5661) into himin all things, which is (5748) the head, even Christ: 16 From whom thewhole body fitly joined together (5746) and compacted (5746) by that whichevery joint supplieth, according to the effectual working in the measure ofevery part *, maketh (5731) increase of the body unto the edifying of itselfin love."
In short we are born with some understanding of good and bad, but with life experience we learn more, make better decisions, but we do that with Gods understanding of the world, because Gods Holy Spirit is the one teaching us. The spirit of the world, doesn't teach us, nor can it help us to grow up. So lets build our love up, for this is growing up!
