"For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them." Ephesians 2:10, NASB
"The LORD is my shepherd,
I shall not want.
He makes me lie down in green pastures;
He leads me beside quiet waters.
He restores my soul;
He guides me in the paths of righteousness
For His name's sake.
Even though I walk through the valley of the shadow of death,
I fear no evil, for You are with me;
Your rod and Your staff, they comfort me."
Psalm 23: 1-4, NASB
