Revelation 2:26

“And he who overcomes, and keeps My works until the end, to him I will give power over the nations –

1 King 6:12  ….if you walk in My statutes, execute My judgments, keep all My commandments, and walk in them, then I will perform My word with you, which I spoke to your father David.

John 6:19  Jesus answered and said to them:  “This is the work of God, that you believe in Him whom He sent.”
