How to heal and be healed

Surely He took our infirmities and carried our sicknesses.  By His wounds we are healed.
The Prophet Isaiah

Do you believe that Jesus is the Son of God, and that He died for your sins?  If so, you know that your sins were immediately forgiven and forgotten, as if they never happened, the moment you believed.  Period.  Jesus' death for us is a historical fact.  Even if you don't feel forgiven, that wouldn't and couldn't mean Jesus didn't die and rise from the dead.  He is our Savior.

But did you know that He's also our Healer?

Yes, His salvation is not just so we can be forgiven for sins, it's also so that we can be healed from sicknesses, as it is written,

"Praise the LORD oh my soul and forget not all of his benefits.  Who forgives all of your sins and heals all of your diseases..."  King David

The same God who forgives all sin also heals all diseases.
All sin.
All diseases.

How? 
Faith.

If you can believe God to forgive you, the same belief also heals you.
This is how you are healed:  Trust in Jesus as your healer in the same way you trusted him as your Savior.

And this is how you heal:  Share the good news about Jesus as the Healer in the same way you shared the good news about Jesus as Savior.

If the sinner accepts Jesus as Savior, he or she is saved.
If the sick person accepts Jesus as Healer, he or she is healed.

All you do is share the good news.  If the one who hears believes, he or she will be saved...and healed.
