Those who belong to Christ Jesus have nailed the passion and desires of their sinful nature to his cross and crucified them there.
It's hard to imagine nailing your sins to the cross. After all, Jesus did all of the work. He's the one who was tortured, hung up, and killed-- not us-- not really.
So, it's hard to imagine that the way to salvation is the do something so simple-- believe and ask Jesus into your heart.
It's magical and spiritual... and hard to understand especially if you haven't been to church all of your life (and sometimes if you have).
Jesus did all of that so we wouldn't have too-- so we could go to Heaven with him. When you ask for forgiveness, it's like those sins are nailed to the cross, no longer part of us.
So simple, but so powerful
God Bless You,
