Week 2 - 1 John 2:18 - 3:10
Short study of John's Epistles (1 John - 3 John)
Warnings Against the Antichrist (1 John 2:18-27)
The word ‘antichrist’ occurs in the Bible only in the Johannine letters (1 John 2:18, 22; 4:3; 2 John 7), but the conception is found elsewhere.
Light is shed by this verse upon two important doctrines: the perseverance of the saints and the nature of the church. ‘He who stands firm to the end will be saved’ (Mark 13:13), not because salvation is the reward of endurance, but because endurance is the hallmark of the saved. If the false teachers had belonged to us, they would have remained with us. This is stated as a principle. Those who belong to us stay with us. Future and final perseverance is the ultimate test of a past participation in Christ (cf. Heb. 3:14). ‘Those who fall away’, on the other hand, ‘have never been thoroughly imbued with the knowledge of Christ but only had a slight and passing taste of it’ (Calvin).
the theological error he is combating is defined more precisely as a denial that ‘Jesus Christ has come in the flesh’, or, as perhaps this expression should be translated, a denial that ‘Jesus is the Christ come in the flesh’. The antichrists probably taught (as some later Gnostics certainly taught) that Jesus was born and died a man, and that ‘the Christ’, by which they meant a divine emanation, was within him only during his public ministry, descending upon him at his baptism and leaving him before the cross. They thus denied that Jesus was or is (estin, 22) the Christ or the Son. They made him a mere man who for a brief period was invested with divine powers or even adopted into the Godhead, but they denied that the man Jesus and the eternal Son were and are the same person, possessing two perfect natures, human and divine. In a word, they denied the incarnation.
21 And as for me, this is my covenant with them, says the LORD: my spirit that is upon you, and my words that I have put in your mouth, shall not depart out of your mouth, or out of the mouths of your children, or out of the mouths of your children’s children, says the LORD, from now on and forever.
Children of God
26 A new heart I will give you, and a new spirit I will put within you; and I will remove from your body the heart of stone and give you a heart of flesh. 27 I will put my spirit within you, and make you follow my statutes and be careful to observe my ordinances.
