And may the God of peace Himself sanctify you through and through [separate you from profane things, make you pure and wholly consecrated to God]; and may your spirit and soul and body be preserved sound and complete [and found] blameless at the coming of our Lord Jesus Christ (the Messiah). Faithful is He Who is calling you [to Himself] and utterly trustworthy, and He will also do it [fulfill His call by hallowing and keeping you]. ~ 1 Thessalonians 5:23-24 AMP

My son, do not forget my teaching, but keep my commands in your heart, for they will prolong your life many years and bring you peace and prosperity. ~ Proverbs 3:1-2 NIV

Rejoice in the Lord always. I will say it again: Rejoice! Let your gentleness be evident to all. The Lord is near. Do not be anxious about anything, but in every situation, 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. ~ Philippians 4:4-7 NIV
