I have never felt truly secure with my salvation. I set a high standard for myself, and have a tightrope salvation. Instead of being happy I am saved, I get terrified, being afraid that if I sin that I am going to hell, as if salvation is “lost” on a day to day basis, then it comes down to how good I am on that particular day. If I sinned, then I’m not damned. If I didn’t, then I’m not. I get terrified and feel God is extremely angry at me when I sin. This a miserable way of life. Any advice help will be appreciated. It’s as if I’m walking on eggshells all the time.
To lose your salvation, Jesus would to go back in time and be uncrucified. Your problem is common, you think that salvation is your business. It's not. It is God's. Psalm 3:8, "Salvation belongs to the Lord" and 1 Corinthians 1:30 "It is because of Him (God) that you are in Christ Jesus, who has become for us wisdom from God: our righteousness, holiness, and redemption."
God put us into Christ. He does not see you any more. You died and you life is hidden in Christ with God. (Colossians 3:3). Salvation does not depend on your behaviour. If it did, no one could be saved. No one is good enough.
Quit looking at yourself apart from Christ. If it's good enough for God, let that be good enough for you. Otherwise you are insulting God by saying that the death and resurrection of His Son is not enough. Make the cross of Christ your cross too. That is what really happened spiritually. Confess your sin as soon as you realise what you have done and thank God that Jesus has already paid the price.
Study, memorise and declare Galatians 2:20 - out loud. Every day. Find other verses that establish you in Christ. This is the new birth right of the believer. This is the glorious inheritance of the saints, which is for now, not in heaven when we die. Sure, there is an outworking of this during our time on earth. But we must have a solid foundation or we will be constantly living in doubt and unbelief. And that is the sin that grieves God the most.
