BLESSED ASSURANCE; There are ASSURANCE for people who trust and believe in God.
It’s not denomination that will save people; you can be Catholic, Methodist, Baptist, Pentecostal; or even Muslim, your faith is important.

But, to be a child of God is what makes difference. If you want to be a child of God; you have a role and responsibilities to play. God too will play His role by making you His favorite like He did to all our heroes of faith like Father Abraham, Sarah, Joseph, Daniel, David, just to mention a few in the Bible.
