But according to point 4, Irresistible Grace, why bother? It has been predetermined that they will be saved or not, no action or inaction by man can change that, right? If this Church wasn't handing out Thanksgiving baskets (and slapping themselves on the back for doing so), the lost that will be saved are still going to be saved...at least according to Calvin.
Because God may intend someone to be saved as a result of another's action.
I was saved as a result of hearing the Word of God. The Holy Spirit gifted me with faith as a result of someone preaching it.
God led both one to preach and another to be saved.
“why bother?”
Can a plant grow where a seed hasn’t been planted?
(that’s why we Christians are needed... seed planting)
using the same logic...
Once we plant a seed, do we get to decide whether that seed grows?
(that’s God’s job)
