"All that the Father has given me will come to me. And the one who comes to me I will certainly not cast out." (John 6:37)
The other day I was having a conversation with a friend about witnessing to cult members, such as Jehovah's Witnesses. I was asking what his experiences have been like with them and to see what advice he would give me if I ever encountered one. To sum up his advice, "Don't bother. They don't want the truth. Your time would be much more well spent doing something else." During our conversation, I didn't disagree with him because I thought to myself, "He's right! These people are so hardened and blind that there is no point in even bothering."
Later on as I went through my day, I began thinking through this. So often i've been asked the question, "If Calvinism is true, why bother witnessing? Isn't God going to save them anyways?" In fact, a friend of mine just the other day asked me this question. Its a very legitimate question. But its an inconsistent one. Let me explain.
Why would someone give me the advice to not bother witnessing to Jehovah's Witnesses? The obvious answer from their non-Calvinistic perspective would be because they have hardened their own hearts to the point that they are so brainwashed that there is nothing you could possibly say that could persuade them. But what about God? Couldn't He reveal Himself to them? Well, from an arminian perspective, God has already done all He could do. He's died for their sins and He's persuaded them with His Holy Spirit. Now its up to them to respond!
So when people ask me, "If Calvinism is true, why bother witnessing?" I simply ask in return, "If Calvinism isn't true, why bother witnessing?" If God has done all He could do, and if cultists have hardened themselves to the point of us giving up, then what more could we possibly do? In fact, why should we even pray for them? After all, its all up to them now!
But as I got to thinking through this, I was reminded of John 6:37, where the Father decrees the giving of of His chosen people to the Son; all that the Father gives to the Son will come to the Son. Is it possible that it could happen any other way? Could there be disunity in the Godhead? Could the Father command something of the Son that couldn't be accomplished because of the "almighty" will of man? Of course not! So how could I even think of believing that there are people out there that are too "hard" for God to save? My God can save anyone He wills to save! And yes, this includes even the most hardened Jehovah's Witness.
"But Mike! You are being inconsistent! If these people aren't God's 'chosen ones,' then you are wasting your time!" This could only be true if all of God's elect had glowing halos over their head so that I could distinguish them from the non-elect. But because I don't know who the elect are, I can truthfully and boldly proclaim the Gospel to all men and trusting God to do the rest. After all, Salvation is completely and totally of God and is not in any way dependent upon the will of man. This is called Monergism: God alone saves apart from the cooperation of man's "will."
One good point my friend did bring up that I agreed with is casting pearls before swine. If someone does not want to hear what I have to say, i'm not going to sneak into his bedroom at night, tie him up and scream through a megaphone, "accept Christ!" I think there needs to be a balance here. But if you know a Mormon or a Jehovah's Witness who seems set in his beliefs, it is in no way a waste of time to share with him, even if it takes years. It would be absolutely wrong to conclude that this person is just like any cultist who refuses to even listen to what you have to say. And furthermore, this person may possibly have never heard the Gospel! Just because they proclaim Christ and his love, this doesn't mean that they know the true Gospel. We can never assume anything. Proclaim the truth, because God is always glorified when His truth is proclaimed. This is just one of many reasons why i'm a Calvinist.
