Read Titus 1
“... in hope of eternal life which God, (who cannot lie,) promised before time began,”
Titus 1:2 And here is another great truth in Hebrews 6:18 - "It is impossible for God to lie.”
These are great faith building verses that I frequently use in prayer. Think about this. God cannot lie!
2 Corinthians 1:20 says “For all the promises of God in Him are Yes, and in Him Amen, to the glory of God through us.”
I would strongly recommend that you memorize these verses to heart, and use them boldly in your prayers. Our God wants us to have strong confidence in Him! Amen!
