Once saved always saved

ANSWER:

Yes, Once saved always saved is the correct doctrine and God even triples it three times to prove His point.

• John 10:28. Jesus Christ God, the son says that once He gives life, it’s eternal not temporary or conditional under some sin and no one can pluck them out of His hand.
• John 10:29 shows that the Father also does the same as well.
• Ephesians 1:13-14 shows that God, the Holy Spirit also seals the person, all the way till they go to glory.
• Romans 8:33-35 is definite proof that no matter who condemns you for your sin, God still justifies and nothing can separate you from that.
• Romans 8:38-39 further proves the point that whatever you do in the future, or in present or whoever condemns you, nothing can separate from you being in Christ.
