'Believing' in the Bible

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,

So too then, at the present time there has come to be a remnant [a small believing minority] according to God’s gracious choice.

May the God of hope fill you with all joy and peace in believing [through the experience of your faith] that by the power of the Holy Spirit you will abound in hope and overflow with confidence in His promises.
