"Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God's power are being guarded through faith for a salvation ready to be revealed in the last time.
In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faith--more precious than gold that perishes though it is tested by fire--may be found to result in praise and glory and honor at the revelation of Jesus Christ.
Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, obtaining the outcome of your faith, the salvation of your souls."
- 1 Peter 1:3-9
"For this is the love of God, that we keep his commandments. And his commandments are not burdensome."
- 1 John 5:3
"Rejoice in the Lord always. Again, I will say: Rejoice!
"God wants you happy, but he doesn't do it with circumstance. He does it with himself. He does it with the gospel. He does it in-and-through circumstances. This is a call for faith - huge faith. That God is good, God is for us, God is using all these things for our deep happiness now, and our perfect, unsullied happiness in the age to come."- John Piper
Let your reasonableness be evident to all. The Lord is near. Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things... practice these things, and the God of peace will be with you."
- Philippians 4:4-7
