Is Your Faith Just an Intellectual Agreement?
One of the reasons why people can't believe that salvation is by faith is because of their misunderstanding of what faith is. To them, faith is an intellectual assent or mental agreement of a certain proposition. Example: Proposition --- Jesus existed
They think that faith is believing in this proposition, that the Lord Jesus did exist. Of course, to just simply believe mentally that He existed and to be told that you are saved by it is unacceptable.
But that's not what saving faith is in the Bible. Saving faith is trust, reliance, dependence, and confidence in what Christ did on the cross for one's salvation.
You are not asked to believe that He existed, rather, you are asked to trust, rely, depend and be confident about what He did on the cross for your sins on the cross of Calvary.
His work/death on the cross was very real. He did do it. God was satisfied with it so much so that He raised Him back to life. God reckons it as efficient for all time.
That's what you are asked to believe or trust in for your salvation. You are asked to entrust your salvation to what He did on the cross for you; that it was sufficient for your salvation and you do nothing extra, on the side, with the intention and motivation of saving yourself.
Can you trust God if He tells you "I have already provided an all-sufficient payment for all your sins on the cross of Calvary in Christ Jesus?"
