FOURTH: RECEIVE what you believe.
Receive Jesus Christ: (John 1:12)
"But as many as received him, to them gave he power to become the sons of God, [even] to them that believe on his name:"(KJV)
A good illustration of this is the following:
Take a paper currency bill out and hold it and think of what you have just read, like this;
1 Know....you can know this is paper currency
2. Understand....you can understand what it can do,
3. Believe....you can believe it is real
AND
4. Receive....BUT NOT UNTIL YOU RECEIVE IT CAN YOU EXPERIENCE ITS BENEFIT.
