What does the Bible say about hope?

While the world uses "hope" to describe uncertainty, the Bible defines it as a confident assurance with absolutely no doubt attached. This isn't a vague feeling; it's a reality built on the sure foundation of the Lord Jesus Christ and the unchanging Word of God. According to Hebrews 11:1, faith is the "assurance of things hoped for," providing a conviction that the promises of God are already settled. Witness how the biblical hope within you can move from a wish to a "no doubt about it" certainty based on the finished work of Christ.
