Limited Atonement is such a scumbag doctrine.
It appeals to the religious, the racists, and those with prejudice.
It's like the KKK version of the gospel.
Let's walk this out.
If God chooses to save some and not others, so what? How would that change the divine imperative for the sons of God to be led by the Spirit of God?
Don't want to go to Nineveh to bless the people who harmed you? So what? You should hope that God sends a fish to deliver you vs. choosing another to go.
You, as an apostle, prefer to be around people of your own race? So what? You should hope that God sends another to oppose you to your face and not simply dismiss you.
But now, Limited Atonement inserts man's reasoning into the mix.
"The people have a history of rejecting God? There is no way God will send me to them."
This person has NO CHANCE to be led by the Spirit in this matter.
"This guy is a Democrat. Everything he says is a lie."
Zero chance God will use you in his life.
If one is led by the Spirit they might even be led to people who will reject the gospel completely. (gasp!)
"What?! God will never waste my time!"
Ha, buddy, if you were really bought for a price you should know that it's not your time to begin with. Obviously God has something to teach you. If you will not be led by the Spirit in faith then you can learn nothing.
Limited Atonement: Such a stupid, stupid doctrine. Ironically, those who use it to quickly cut others off from God's grace are, themselves, cut off from God's Spirit. The way of the sons of God is to be led by the Spirit of God, not by reason. Reason how to cut your lawn and how to make a cake NOT how God distributes His grace.
If you're caught in this doctrine pray that God sends you a big fish or one to oppose you to your face so that you will repent. If you keep going this way you'll turn bitter and be of no use for God.
