Take the helmet of salvation...
A soldier's helmet protected his skull and neck from his enemy's weapons and falling objects. It also identified the soldier to whom he had allegiance to.
A person can survive most injuries depending on the severity; a broken arm, a missing limb, a stubbed toe all of which are painful but survivable. But head trauma is different. It doesn't take a neuroscientist to point out that head injuries are the most traumatic injuries a person can sustain. Head injuries can cause aneurysms, hemorrhages, hematomas and several other big fancy scary medical terms.
We, Christians, for decades have put an emphasis on salvation being something God offers and we accept. Not necessarily as a life changing new identity that we often tote as a "free gift". But more or less like an added credit card to our wallets.
God: "Do you want to accept this Heaven Express Platinum Card with a very low APR offer? We can also roll all your credit cards into your new Heaven Express Platinum Card in order to make your payments quick and easy. If you act now we'll give you this special bonus of touring our location once this card has expired. What do you say?"
Us: "Yes, sign me up today!"
Then as we incur the dept we work hard at paying it off. We don't make any true changes except for who we are in "debted" to. We pay off that debt by trying to have better behavior around church people and give Jesus a shout out now and then. But what happened to the life change?
As often as you read in Scripture where salvation is a discussed topic it mostly describes a new life or a transformation taking place. Salvation isn't found in a nod of agreement to a doctrine but in a life transformed by the person of Jesus Christ.
So if we get this salvation wrong we screw up how we view God, what we think about God, how we respond to God, and what we do for God. It's like a hemorrhage that leads to a spiritual coma. That is why it is so crucial for us to understand that salvation is meant to be worked out and lived daily.
I do accept what Jesus has done for me; that is just the beginning. Who I am is a representation of the salvation that has renewed my mind, transformed my heart, and opened my life up to a divine purpose.
