And indeed I count all things as loss because of the excellency of the knowledge of Christ Jesus my Lord, for whose sake I have lost all things, and count them as rubbish, that I may gain Christ, 9 and be found in him, not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness that is from God through faith; 10 that I might know him, and the power of his resurrection, and the participation of his sufferings, becoming like him in his death, 11 if in any way he might come to the resurrection from the dead.
Philippians 3:8-11
And likewise you also rejoice and be glad with me.
Philippians 2:18
Rejoice in the Lord always. Again I say: Rejoice!
Philippians 4:4
