Happiness is…
That you, being rooted and grounded in love, may have strength to comprehend with all the saints the breadth, length, height, and depth, and to know the love of Christ that surpasses knowledge, so that you may be filled with all the fullness of God. (Ephesians 3:17–19)
Profound and intense happiness
Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory. 1 Pietro 1:8 KJV)
The key to happiness
Live in peace; and the God of love and peace will be with you. (2 Corinthians 13:11)
