So, I assume you never choose to sin now, since the Spirit won't let you? We have this thing called free will...
Thing is, my salvation is not dependent on my performance (Romans 3:20, Romans 4:5, Galatians 2:16).
So the only way my sinning is going to put me out of the kingdom is going to be if its deceitfulness hardens me to God so that I depart from God.
And that's not possible if I have the fear of the LORD in me (Jeremiah 32:38-40 (kjv), Psalms 19:9 (kjv))
What saves me is not my abstention from sinning; but my faith.
Since I am sealed by the Holy Spirit (Ephesians 1:13-14, 2 Corinthians 1:22, 2 Corinthians 5:5), I am also sealed in faith (Galatians 5:22-23, 1 Corinthians 12:9) unto the day of redemption (Ephesians 4:30).
Because I hear Jesus' word and believe on Him who sent Him, I
shall not come into condemnation but have passed from death unto
everlasting life (John 5:24 (kjv)).
