ἐπίγνωσις

Romans 1:28 ἐπιγνώσει, knowledge,

Furthermore, since they did not see fit to acknowledge God, He gave them up to a depraved mind, to do what ought not to be done.

Here: Recognition that leads to admitting it. Paul has already said they 'knew God' (1:21). Their failure was refusing to acknowledge what they knew, not a lack of information.

Romans 3:20 ἐπίγνωσις [is] knowledge

Therefore no one will be justified in His sight by works of the law. For the law merely brings awareness of sin.

Here: Recognising sin as sin: identifying it clearly as a breach of God's stated will. There is no verb in the Greek; English supplies 'is' or 'comes'.

Romans 10:2 ἐπίγνωσιν. knowledge.

For I testify about them that they are zealous for God, but not on the basis of knowledge.

Here: Recognising and acknowledging something, here what God has done. It is not a lack of learning; v.3 spells it out as not recognising 'God's righteousness', which Paul ties to Christ in v.4. Paul is echoing Hosea's charge that Israel lacked the 'knowledge of God' (Hos 4:1, 6).

Ephesians 1:17 ἐπιγνώσει [the] knowledge

that the God of our Lord Jesus Christ, the glorious Father, may give you a spirit of wisdom and revelation in your knowledge of Him.

Here: Knowledge directed at a person: recognising and acknowledging God, not collecting information about him.

Ephesians 4:13 ἐπιγνώσεως knowledge

until we all reach unity in the faith and in the knowledge of the Son of God, as we mature to the full measure of the stature of Christ.

Here: Knowing a person by recognising and acknowledging him, not just holding facts about him. Ephesians uses the word for knowing God himself (1:17).

Philippians 1:9 ἐπιγνώσει knowledge

And this is my prayer: that your love may abound more and more in knowledge and depth of insight,

Here: Knowledge as real acquaintance and recognition. In Paul it usually means knowing God and his will (compare Col 1:9–10). It is not abstract information but knowledge that shapes how a person lives.

Colossians 1:9 ἐπίγνωσιν knowledge

For this reason, since the day we heard about you, we have not stopped praying for you and asking God to fill you with the knowledge of His will in all spiritual wisdom and understanding,

Here: Knowledge aimed at a definite object: recognising and acknowledging God's will, not just holding information about it. It is in the accusative because it is the content they are filled with.

Colossians 1:10 ἐπιγνώσει knowledge

so that you may walk in a manner worthy of the Lord and may please Him in every way: bearing fruit in every good work, growing in the knowledge of God,

Here: This picks up 'knowledge of his will' from 1:9. It is the knowledge of God that works its way into conduct, either as the means by which they grow or as the area in which they grow.

Colossians 2:2 ἐπίγνωσιν [the] knowledge

that they may be encouraged in heart, knit together in love, and filled with the full riches of complete understanding, so that they may know the mystery of God, namely Christ,

Here: Knowledge as recognising and grasping something that has been made known. In Colossians the word carries the sense of knowing God that shapes how a person lives (1:9–10; 3:10).

Colossians 3:10 ἐπίγνωσιν knowledge

and have put on the new self, which is being renewed in knowledge in the image of its Creator.

Here: Knowing God and his will as someone personally engaged, a knowing that shapes how you live. Colossians has used the word repeatedly (1:9, 1:10, 2:2) against a rival "philosophy" that offered higher knowledge.

1 Timothy 2:4 ἐπίγνωσιν [the] knowledge

who wants everyone to be saved and to come to the knowledge of the truth.

Here: Recognition or acknowledgment of something. Joined with "of the truth", it is a set phrase in the letters to Timothy and Titus for coming to accept the gospel, in other words conversion. It is not general learning.

2 Timothy 2:25 ἐπίγνωσιν a knowledge

He must gently reprove those who oppose him, in the hope that God may grant them repentance leading to a knowledge of the truth.

Here: Recognising and owning the truth. It is not just having information. In these letters it is close to a set phrase for coming to the faith.

2 Timothy 3:7 ἐπίγνωσιν a knowledge

who are always learning but never able to come to a knowledge of the truth.

Here: Recognition and acknowledgment of something, knowledge that takes hold of it. In the Pastoral Letters (1 and 2 Timothy, Titus), 'come to the knowledge of the truth' is a set phrase for accepting the gospel, close to what we would call conversion.

Titus 1:1 ἐπίγνωσιν knowledge

Paul, a servant of God and an apostle of Jesus Christ for the faith of God’s elect and their knowledge of the truth that leads to godliness,

Here: Recognising and owning the truth, not just knowing about it. In these letters 'coming to the knowledge of the truth' is a standard way of saying someone has turned to the gospel.

Philemon 1:6 ἐπιγνώσει [the] acknowledgment

I pray that your partnership in the faith may become effective as you fully acknowledge every good thing that is ours in Christ.

Here: Knowing that recognises something and responds to it, not just having information. Philemon needs to see clearly, and act on, the good that belongs to believers.

Hebrews 10:26 ἐπίγνωσιν knowledge

If we deliberately go on sinning after we have received the knowledge of the truth, no further sacrifice for sins remains,

Here: Knowledge that recognises and accepts something, not just information you hold. In the stock phrase 'knowledge of the truth' it describes conversion to the Christian message.

2 Peter 1:2 ἐπιγνώσει [the] knowledge

Grace and peace be multiplied to you through the knowledge of God and of Jesus our Lord.

Here: Knowing God and Jesus in a personal, committed way. It has its roots in the moment they came to recognise and acknowledge Jesus as Lord when they turned to the faith. It is a key word in this letter.

2 Peter 1:3 ἐπιγνώσεως knowledge

His divine power has given us everything we need for life and godliness through the knowledge of Him who called us by His own glory and excellence.

Here: Knowing a person, in particular coming to know and acknowledge God or Christ when one became a believer. It is a keyword of the letter (1:2, 3, 8; 2:20) and is relational and decisive, not abstract information.

2 Peter 1:8 ἐπίγνωσιν.¶ knowledge.

For if you possess these qualities and continue to grow in them, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ.

Here: In 2 Peter (1:2, 1:3, 2:20) this is the knowing of God and Christ that brought the readers into the faith. It is recognition of Jesus and commitment to him, not information about him. The virtues make this knowing productive instead of dormant.

2 Peter 2:20 ἐπιγνώσει [the] knowledge

If indeed they have escaped the corruption of the world through the knowledge of our Lord and Savior Jesus Christ, only to be entangled and overcome by it again, their final condition is worse than it was at first.

Here: 2 Peter's key word for the knowing that happens at conversion (1:2, 3, 8): recognising Jesus and owning him as Lord. It is the same word the letter uses for the knowledge through which God gives "everything needed for life and godliness" (1:3).
