Grace Vs Works- Once Saved ,Always saved?

With the holiness movements all over the world, not just Prophet Owuor but many,many others. How you dress can take you to hell, not tithing can take you to hell, now for sure Jesus Christ said, not all who call me Lord will enter my kingdom. My fellow believers what is your take on this matter. Is salvation a free gift received by faith or is faith without works dead?Is the righteousness of men like a filthy rug to God because of how holy He is? Or is the main thing our good works? Will the thief who repents at the last minutes of his/her life enter heaven or will all who lived an unholy life not see God . Here is a critic of such a holiness movement by a proponent of grace. Then the debate from two Christian scholars with substantiating scriptures.

you are saved from what? salvation lies within,

Yes, once you’re saved always saved. What are we saved from? Unbelief. To obtain salvation all you have to do is repent and believe that your faith in Jesus will carry you into eternal life. Sin is unbelief.

In summary, John 10:28-30, Jesus says: “I give them eternal life, and they shall never perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all; no one can snatch them out of my Father’s hand.

The Bible teaches both: believe and do as you are required. Do not go back to your sinful nature.

Armenianism and Calvinism are both right but since they both rely on the scriptures I say I am both.
