In Philippians Paul talks about the believers in Philippi being pressured to accept the doctrine that one has to follow the rules of the law of Moses in order, to be saved.
The subtle difference of course is how “love is the fulfilling of the law”, so those who are saved and born again – “transplanted from the kingdom of darkness to the kingdom of light” follow the law of Moses in Spirit, just as Jesus pointed out in His ‘Sermon on the Mount’, it’s not really good enough to not murder, but don’t be angry at someone – or someones – without cause, i.e. disliking them.
The one’s insisting the seat of Jesus (who IS salvation) be shared with the seat of Moses, at their authority, Paul said, were acting like dogs. How do dogs act? They are always pushing each other to be leader of the pack, to be dominant.
Jesus said that’s the way the world is and believers should not be that way.
Also in his letter to the Philippians, Paul wrote there was only one way to remain pure and blameless – “I pray that your love will overflow more and more, and that you will keep on growing in knowledge and understanding, that you would distinguish those things that are suitable, that you may be pure and blameless for the day of Christ”.
“…the washing with water through the word, to present to Himself a glorious church without spot or wrinkle or any such blemish, but holy (including whole) and blameless.” – Ephesians 5:27-28
Sealed Foreheads? of Revelation 7:1-4, and 9
After this – the opening and first appearance of Seal 6 – I saw four angels standing at the four corners of the earth, holding back its four winds so that no wind would blow on land or sea or on any tree. And I saw another angel ascending from the east, with the seal of the living God. And he called out in a loud voice to the four angels who had been given power to harm the land and the sea: “Do not harm the land or sea or trees until we have sealed the foreheads of the servants of our God.” And I heard the NUMBER of those who were sealed, 144,000 from all the tribes of Israel… ..After this I looked and saw a multitude too-large-to-count, from every nation and tribe and people and tongue..
….Revelation 9:4 – “…only those who do not have the seal of God on their foreheads..”
