For when we place our faith in Christ Jesus, there is no benefit in being circumcised or being uncircumcised. What is important is faith expressing itself in love – Galatians 5:6NLT
The most important reason why Jesus had victory (all the time) over Satan was because of love. He was love personified. Love is light because the bible says in Him was life and that light was the life of man (John 1:4). So each time Jesus showed up, love showed up, light showed up and darkness disappeared.
Your faith in the finished works of Jesus Christ overcomes the world coupled with love because love never fails. Your faith might stumble somehow but love will never stumble. There is no judgment against love because perfect love casts out fear. You will not fail because greater is the LOVE of God in you than the HATRED of Satan in the world.
You want to win in life all the time? Walk by faith in love.
