I took some time to research Calvinist theology and I would say I’m leaning toward this doctrine more than Arminian.
I used to believe that Christ atoned for all people. I now accepted Christ death is only for the elect and I’ll tell you why.
If Christ died for all people, then that means all people would be saved. If some people end up in hell, then that means Christ death didn’t include them in the atonement. If Jesus Christ suffered for all, but only some people believe and the rest are lost, then that means Christ suffered for nothing.
For example, we read in scripture in 1 Tim that God desires all to be saved right? Does all include everyone? Or only the believers?
Here is where the paradox lies. God desires for all to be saved, but yet He has only elected some. This means that what God has plan is not always what He desire.
Once you study more in depth you will understand why Reformed theology makes more sense.
