You can never make yourself something that you're not. If you're just impersonating Christianity, no matter if you're preaching the Gospel, you need an altar call in your soul. That's right. If you're just trying to act like that person that's a Christian, you're miserable yourself, knowing in your heart that you're not.
And if the fruits of the Spirit don't follow you: longsuffering, goodness, meekness, gentleness, patience, then you need an altar call in your heart. You just feared hell and started off trying to be a Christian. God has to call you to be a Christian. God called Abraham. Give him…elected him.
