“That the communication of thy faith may become effectual by the acknowledging of every good thing which is in you in Christ Jesus.”
Philemon 1:6

In Christ Jesus, there are good things in you, and like Jesus, you should be able to say satan has nothing in you:
“…for the prince of this world cometh, and hath nothing in me.” John 14:30
Everything that was contrary to the purposes of God passed away with the old man, as a new creation in Christ, all things have become new and those new things are of God:
“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. And all things are of God…” 2 Corinthians 5:17-18
And the Bible tells us that God gives good and perfect gifts:
“Every good gift and every perfect gift is from above, and cometh down from the Father of lights…” James 1:17
He wants you to recognize the good things in you- every one of them. Firstly, contemplate on this fact- as a born again child of God, in Christ, you have good things inside you.
