'Personal' in the Bible

I am not ashamed of the gospel, for it is the power of God for salvation [from His wrath and punishment] to everyone who believes [in Christ as Savior], to the Jew first and also to the Greek.

This righteousness of God comes through faith in Jesus Christ for all those [Jew or Gentile] who believe [and trust in Him and acknowledge Him as God’s Son]. There is no distinction,

The faith which you have [that gives you freedom of choice], have as your own conviction before God [just keep it between yourself and God, seeking His will]. Happy is he who has no reason to condemn himself for what he approves.
