John 17:3 And THIS is Life Eternal, that they might KNOW Thee the ONLY True God, and Christ the Saviour, whom Thou hast sent.
1 John 2:1-7
2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
2:2 And he is the atonement for our sins: and not for ours only, but also for [the sins of] the whole world.
2:3 And hereby we do know that we know him, IF we keep His Commandments.
2:4 He that saith, I know him, and keepeth NOT His Commandments, is a LIAR, and the truth is NOT in him.
2:5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
2:6 He that saith he abideth in him ought himself also so to walk, even as he walked.
2:7 Brethren, I write no new commandment unto you, but an old Commandment which ye had from the Beginning. The old Commandment is The Word which ye have heard from the Beginning.
