“All the promises of God find their Yes in Him. That is why we utter the Amen through Him, to the glory of God”
2 Corinthians 1:20 (RSV)
“Amen” means, “Yes, Lord, you can do it.”
It means, “Yes, Lord, you are powerful.
Yes, Lord, you are wise.
Yes, Lord, you are merciful.
Yes, Lord, all future grace comes from you
and has been confirmed in Christ.”
“Amen” is an exclamation point of hope after a prayer for help.
