Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through the sanctification of the Spirit and belief of the truth.
2 Thessalonians 2:13
And by their prayer for you, which long after you for the exceeding grace of God in you. Thanks be unto God for his unspeakable gift.
2 Corinthians 9:14-15
