2 Corinthians 1:20-22 (NIV)
For no matter how many promises God has made, they are "Yes" in Christ. And so through him the "Amen" is spoken by us to the glory of God. Now it is God who makes both us and you stand firm in Christ. He anointed us, set his seal of ownership on us, and put his Spirit in our hearts as a deposit, guaranteeing what is to come.
My pastor says that as we read the Bible, we should ask these questions: what did it mean then?, how does it apply today?, and what should I do in response? In answer to that last question, he says we should look for one of four opportunities: is there an example to follow?, is there a sin to avoid?, is there a command to obey?, or is there a promise to claim?
The Bible is full of God's promises. Some are unconditional. Others are conditional upon our behavior. The wonderful thing is that none of God's promises are conditioned upon how God feels. God does not change. He is not capricious. It is not immediately evident, but if you examine the promises, you also find that all of them are fulfilled by or are connected to Jesus Christ. He is the central story of the Bible.
One of his promises is that he will not allow any of those who come to him to be lost. For the one who comes to Jesus Christ, there is a guarantee of heaven.
I say Amen to that!
