The doctrine on here can get very confusing.
On one hand, people tell us that Gentiles are responsible for keeping 4 commandments, yet they tell us we only have 2 commandments, which is what Christ taught: loving God and loving our neighbor as ourselves.
then they tell us we only have 1 commandment: 1 John 3:23
is it 4? is it 2? Is it 6? Is it 1? 7?
4 commandments from the written Law of Moses were necessary for the early Gentile converts. Acts 15:28-29
2 commandments from the "spirit" of the written Law of Moses are necessary for the early Christian Gentiles and the Christian Jews. Luke 10:25-27
1 commandment for all Christians, which is actually two commandments in one.
To believe in Jesus Christ
requires obedience to His commandments.
1 John 3:23-24
And this is his commandment, that we should believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. 24 All who obey his commandments abide in him, and he abides in them. And by this we know that he abides in us, by the Spirit that he has given us.
Luke 6:46
Why do you call me ‘Lord, Lord,’ and do not do what I tell you?
Matthew 7:22-23
On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many deeds of power in your name?’ 23 Then I will declare to them, ‘I never knew you; go away from me, you evildoers.’
Luke 13:25-28
When once the owner of the house has got up and shut the door, and you begin to stand outside and to knock at the door, saying, ‘Lord, open to us,’ then in reply he will say to you, ‘I do not know where you come from.’ 26 Then you will begin to say, ‘We ate and drank with you, and you taught in our streets.’ 27 But he will say, ‘I do not know where you come from; go away from me, all you evildoers!’ 28 There will be weeping and gnashing of teeth when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and you yourselves thrown out.
