Know therefore that the Lord thy God-.-.-.-keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations. —Deuteronomy 7:9
God promised that any of His enemies who came against Abraham must inevitably face the Lord, not just Abraham. God will fight your battles for you when you walk in covenant with Him.
When you walk in covenant, you can be confident in possessing the promises of God in your life—{jcomments off} and prosperity all belong to you.
He has given you His Word that when you are weak, He will give you His strength. When you have no ability, He will give you His ability (2 Corinthians 12:9-10). Philippians 4:13 promises that you can do all things through Christ, who strengthens you.
What a glorious exchange:
• His strength for your weakness
• His healing for your sickness
• His salvation for your sin
• His deliverance for your bondage!
Lord Jesus, I lay down all that I am not in exchange
for all that You are. I am not able, but You are.
I am not sinless, but You are. I am not strong,
but You are. I receive all that You are. Amen.
