“If your heartache is for your own personal change, or for change in your marriage, or change in your prodigal children, or in your church, or in the systemic structures of injustice, or in the political system, or in the hostilities among nations, or in the human degradation of the environment, or in the raunchiness of our entertainment culture, or in the miseries of the poor, or in the callous opulence of the rich, or in the inequities of educational opportunity, or in arrogant attitudes of ethnocentrism, or in a hundred areas of human need caused by some form of human greed– if your heart aches for any of these, then you should care supremely about the new birth.
There are other ways of shaping culture and guiding behavior. But none so deep. None so far-reaching. None so universally relevant. None so eternally significant.
Someday, at the return of the Lord Jesus, the world will be made new. The kingdom of God will come fully. Jesus Himself will be the great all-satisfying Treasure in that new and beautiful earth. But not everyone will enjoy it.
‘Truly, truly,’ Jesus said, ‘unless one is born again He cannot see the kingdom of God’ (John 3:3). Jesus is the way, the truth, and the life (John 14:6). Until we come to Him, we will not have life. Not now. Not ever. God gives eternal life, and this life is in His Son (1 John 5:11).
Whoever has the Son has life (1 John 5:12). His word is reliable: ‘Come to Me that you may have life’ (John 5:40). If you come, you will be truly, invincibly, finally alive.”
