Psalm 107:20 (NKJV) He sent His word and healed them, and delivered them from their destructions.
The cross is an avenue for God to get involved in all of our affairs. It is a doorway for physical, emotional, and spiritual healing. It is a passageway for God to bless His children. In the past, I never fully understood this. I always thought if I did good, it gave God the opportunity that He needed to bless me. All along it was the cross, that gave Him that opportunity---nothing else, just the cross. The cross is the grace of God.
I have always appreciated the Scripture at the top as a healing promise, but it is much more than that. The cross is our deliverance from our own destructions. No matter what we have messed up (or ever will mess up), God can, and wants to fix it. It is the very reason He sent His Son(1) in the first place. To heal us, and fix our mistakes.
If you have been paying for some kind of mistake, look to the cross. It is your solution---no matter what problem you got yourself into. Maybe health problems because of smoking or money problems because of debt. It was all paid for on the cross. And so you don't keep getting into these places, ask God for wisdom. Ask God to multiply His fruit(2) inside you. Ask daily. You will see God fix your mistakes and help you from making more. The cross paid the price so you do not have to.
