“In hope of eternal life, which God, that cannot lie, promised before the world began” (Titus 1:2).
It is glorious to think of spending eternity with Christ in heaven, but it’s also heartbreaking to think of those who will be in the lake of fire forever. Our faith rests on the sure hope of eternal life. We can live our lives for Christ confidently and courageously, knowing that nothing we do for the Lord is ever in vain (1 Cor. 15:58). We have certainty in what we believe and our hope is a complete certainty, a confident expectation. It is a destiny.
Eternal life is both a present possession and a future hope. It doesn’t just begin when you die; we have it at conversion, the moment we trust Christ as our Savior. God is “eternal” (Deut. 33:27), and having “eternal” life means we have been given God’s life, which is Christ in us (Col. 1:27; 3:4). Our future hope of eternal life is in the sense that we confidently look forward to eternal life in its final, victorious form when we’ll be in our eternal home in heaven, having received our eternal, incorruptible, glorified bodies (2 Cor. 5:1), dwelling in Christ’s presence forever (1 Thes. 4:17).
All the truth of the Bible and the hope of eternal life is based in God Himself. Our faith is secure by virtue of God’s unchanging character and the fact that He cannot lie. God is Truth and free from all deceit (Deut. 32:4). Numbers 23:19 says, “God is not a man, that He should lie.” Hebrews 6:18 tells us it is “impossible for God to lie.”
From eternity past, “before the world began,” God promised what He was going to do for those who believed (2 Tim. 1:9; Titus 1:2). God is a promise-keeping God. What He has said, He will do. We can rest in Him because we can count on Him and on His character. When (not if) we find ourselves in heaven one day, we’ll praise Him saying, “The Lord was faithful, faithful to me, faithful to all His promises.” source
