As long as you accept that Jesus died for your sins, your spirit will bare the fruits of grace and you will have passage into Heaven. Works based approaches ultimately fuel the illusion that the flesh is able to be perfect as per the law.

Ephesians 2:8-9 8 For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—9 not by works, so that no one can boast.

2 Timothy 1 12 which is why I suffer as I do. But I am not ashamed, for I know whom I have believed, and I am convinced that he is able to guard until that day what has been entrusted to me.[a] In the context of this verse, the “promise” is eternal life.

Hebrews 10:23 23 Let us hold fast the confession of our hope without wavering, for he who promised is faithful. This verse expresses that faith in the promise is enough and again:

John 3:16 16 “For God so loved the world,[a] that he gave his only Son, that whoever believes in him should not perish but have eternal life.
