Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. - Jude 1:21

No, absolutely not! The Lord Jesus Christ has given us solid promises in His holy word, that are not meant to re-arranged, or misconstrued. As a born again Christian you have the promise of eternal life! Jesus will not go back on his word; He will not condemn you for sins in your Christian walk, nor will he boot you out of his kingdom. One of the most impacting verses about this very topic is in John 6:37: "All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out."
Fear of losing your salvation is a lie Satan wants you to believe! So, you sin after having repented; you have wrong, or impure thoughts, or commit sins after coming to Christ. Well, guess what? So does everyone! Consider what the Apostle Paul says in Romans 7:15: "For that which I do I allow not: for what I would, that do I not; but what I hate, that do I." Paul is basically saying: "I know what the right things are, but those are the things I'm not doing." The best cure for this is to come to Jesus and confess these sins and ask His forgiveness, and get back on the road to repentance. Jesus will NOT keep you out of Heaven because of your sins; He paid too high a price to keep you!
Your salvation is assured by the atoning blood of Christ. God does not make promises only to break them later! Truly, Jesus wants us to be happy and confindent in our salvation. Doubt is a human failing, and struggling to re-interpret Bible verses can not only confuse us, but lead us down a wrong path.
We were all born into sin, but through the atoning blood of Christ, we have salvation. There are days when we wrestle with sin. That's the old man, the old nature in us. In 2 Corinthians 5:17, we are told that we are a new creation, born from a carnal nature. The "old things" that are passed away are the unsaved people we once were. All things that become new is our new life in Christ.
However, this is not an excuse to live a life of non-repentance, or deliberate sin. Jesus Christ died on the cross to pay the price that we could not afford to pay. He paid for our sins, and each time we sin, we crucify him all over again.
God made it very simple for us. there's no need to re-interpret scripture in our heads to believe it has an alternate meaning. Our Lord has given us His word at face value, and there really is no room for doubt. I repeat: there is no room for doubt! Read his word, believe his word, and believe on his son who died for our sins.
John 3:16:
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
There it is, and plain and simple as it can get: whosoever believes shall not perish, but have salvation.
____________________________________________John 10:28-30:
28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
30 I and my Father are one.
Again, the Lord Jesus is speaking to us in a perfectly straightforward manner: No one can pluck you out of God's hand. More importantly, God will not boot you out of heaven, because that would make his word in John 3:16 a lie.
____________________________________________John 6:37:
All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
John 5:24:
Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
Look at the key phrases here: believe, have everlasting life, and more importantly, shall not come into condemnation. Can you lose your salvation? No, absolutely not. God is very clear when he says "shall not come into condemnation."
____________________________________________Hebrews 13:5:
5 Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
This is the Lord talking to us who have been born again. He's telling us that he's not going to leave us, forget about us, go back on his word, or forsake us forever. He says: "I will never leave thee, nor forsake thee."
_____________________________________________John 10:29
29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
Read this verse very carefully.: "no man is able to pluck them out of my Father's hand." Jesus is not going to let go, and he's not going to let anyone take you away from him. Now if Jesus is not going to let anyone take you away from him, it stands to reason that he's not going to toss you aside, or give up on you.
_____________________________________________ 1 John 5:13
These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
Again, God's word is very clear, and very simple: believe and receive. You, as a born again Christian, will have eternal life.
If you are truly struggling, and have not asked the Lord Jesus into your heart to save you, you can follow this simple prayer. God truly hears us when we call upon Him!
