1 John 2:24-25
24 Be sure, then, to keep in your hearts the message you heard from the beginning. If you keep that message, then you will always live in union with the Son and the Father. 25 And this is what Christ himself promised to give us—eternal life.
1 John 2:28
28 Yes, my children, remain in union with him, so that when he appears we may be full of courage and need not hide in shame from him on the Day he comes.
Do you feel alone and hopeless? God will always be with you. He will help you to the very end when Christ comes for his own. The promise of eternal life and union with him is a great encouragement.
