The Word for today is found in Philemon 1:6
6 that the sharing of your faith may become effective by the acknowledgment of every good thing which is in you in Christ Jesus.
I want you to know what it is that you are to acknowledge. You need to begin in the Book of Ephesians starting with Chapter 1, verse 3.
Paul tells us all the wonderful spiritual blessings that have been given to us when we accept Jesus as our savior. These are called positional truths: What you are spiritually in Christ; how God sees us through the blood of Jesus.
You may not feel all the things that God says about you here, but that does not make them less true.
As you acknowledge what you are in Christ by the renewing of your mind, you will start too make it a reality in your flesh.
Knowledge is the key.
