'Happy' in the Bible

Your father Abraham [greatly] rejoiced to see My day (My incarnation). He saw it and was delighted.”

If you know these things, you are blessed [happy and favored by God] if you put them into practice [and faithfully do them].

Jesus said to him, “Because you have seen Me, do you now believe? Blessed [happy, spiritually secure, and favored by God] are they who did not see [Me] and yet believed [in Me].”
