1 Thessalonians 5:23-24: "May the God of peace himself make you perfectly holy and may you entirely, spirit, soul, and body, be preserved blameless for the coming of our Lord Jesus Christ. The one who calls you is faithful, and he will also accomplish it." (God`s faithfulness)  

Galatians 5:6: "For in Christ Jesus, neither circumcision nor uncircumcision counts for anything, but only faith working through love."  

However, you, dear friends, must build yourselves up in your most holy faith and pray in the Holy Spirit. Keep yourselves in the love of God as you await our Lord Jesus Christ in his mercy, who will grant you eternal life. Jude 1:20-21

Psalm 91:4: "With his pinions he will cover you, and under his wings you shall take refuge; his faithfulness is a buckler and a shield."  

I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love. Ephesians 3:16-17

Examine yourselves to see whether you are in the faith; test yourselves. Do you not realize that Christ Jesus is in you—unless, of course, you fail the test? 2 Corinthians 13:5

James 1:3-4: "Because you know that the testing of your faith produces perseverance. Let perseverance finish its work so that you may be mature and complete, not lacking anything."
