The way anyone loses their Salvation, is by deliberate sinning.
Peter deliberately sinned - he claimed he would never deny Jesus, and did.
Many of us deliberately sin - "through ignorance, weakness or our own deliberate fault".
I've read of Christian leaders who've sinned and fallen into temptation. Are you saying they can never be forgiven?
1 Peter 4:12 said... the fiery trial which is to test you..... 1 Corinthians 3:13
Not the usual temptations we all face.
That's what I said - they were facing physical persecution for their faith.
People have always persecuted Christians, just as Jesus said they would, John 15:20, John 16:2-3.
Peter was referring to the forthcoming terrible Day of Judgment, 2 Peter 3:7, the Sixth Seal,- tis generations great test of faith and trust in the Lords protection, which will decide our worthiness to be with Jesus in the Promised Land. Romans 9:24-26
You quoted from 1 Peter.
We have not yet received those gifts in their fullness.
We are
being changed into Jesus' image and likeness - ongoing.
We
are children of God, John 1:12, Romans 8:16 - present tense.
Exodus 32:33 The Lord said; Whosoever sins against Me, I shall blot out of the Book of Life.
You need to know your Bible better! [ I did not use a search to find this truth]
I do.
I also know the difference between the OT and new covenant.
Jesus taught us we should forgive 70x7 - in other words, constantly. It would have been hypocritical of him to say that if his Father condemns someone the first time they sin.
Jesus told us that if we forgive one another God will forgive us - see Lord's Prayer. He wouldn't have said that if he knew that God cut off anyone who had believed then sinned against him.
Paul told us to forgive as God, in Christ, forgave us. What does that mean; forgive once and then forever cut them off?
Satan, - like a roaring lion....has plenty of tricks to get people to do the wrong thing.
Yes, and Jesus tells us to pray for deliverance from evil - see Lord's prayer.
Paul told us to put on the armour of God.
John told us that if we sin we have someone who will intercede for us.
Is being thrown into the Lake of fire for Eternity;= forever separated from God; not annihilation? Revelation 20:14-15
No, it's living forever in the lake of fire.
(Assuming that that's what happens.)
