1 John 5:10-13

Mace(i) 10 he that believeth on the son of God, hath the testimony of God thereto: he that does not believe God, impeaches his veracity, because he does not believe the testimony that God gave of his son. 11 Now what is testified, is this, that God has given to us eternal life: and this life is by his son. 12 he that receives the son, is intitled to life; and he that does not receive the son of God, has no title to life. 13 these things have I written to you, that you may know that you have eternal life, by your believing on the name of the son of God.
