Paul, an apostle of Christ Jesus by the will of God, according to the promise of life that is in Christ Jesus. (2 Timothy 1:1)
There's promise of life in Christ Jesus. Yes, eternal life is promised through him who said, "God is not the God of the dead but of the living." And in this context Jesus was teaching the Sadducees about the resurrection. He said, "At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven. But about the resurrection of the dead - have you not read what God said to you, 'I am the God of Abraham, the God of Isaac, and the God of Jacob' ? He is not the God of the dead but of the living." (Matthew 22:30-32)
Abraham, Isaac & Jacob, though they had died physically when their time on earth was up, they were living eternally, according to these words of Jesus.
Jesus affirmed that again when he spoke to Martha, Lazarus sister. He said,
"I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die......" (John 11:25, 26)
If fact, in the gospel of John, Jesus repeatedly spoke of the promise of eternal life that comes through believing in him.
Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God's wrath remains on him." (John 3:36)
"I tell you the truth, whoever hears my word and believes him who sent me has eternal life and will not be condemned; he has crossed over from death to life. (John 5:24)
For my Father's will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise him up at the last day." (John 6:40)
If you have accepted Jesus as your Savior and are living for him, this promise of eternal life will come true in your lives sooner or later. How blessed and glorious will that day be!
Here's a great verse of exhortation to all of us who have put our trust in Jesus.
Keep yourselves in God's love as you wait for the mercy of our Lord Jesus Christ to bring you to eternal life. (Jude 1:21)
Praise the Lord.
