The Effectual Calling of God(predestination)

In John 6, Jesus said: “No one can come to Me unless the Father who sent Me draws him; and I will raise him up at the last day.” (John 6:44). In this verse Jesus taught that in order for anyone to be able to come to Him, they must be drawn by God the Father. Otherwise, they are unable to accept the Gospel of Christ; they are unable to believe in Him. Now let us look carefully at the second part of this verse. After Jesus said that no one can come to Him unless the Father draws him, He then immediately said, “and I will raise him up at the last day”.
Notice the certainty in the statement where Jesus said, “I will”, which teaches us that those whom the Father draws to His Son will be raised up at the last day. Jesus did not say that those who are drawn must then make the decision to come to Him in order to be saved, as opposed to rejecting Him. However Jesus did say clearly, and without any added conditions or any mention of man’s cooperation, that those whom the Father draws will be raised up at the last day.
John 6:44 is one of several Bible passages we will consider that teach us about the calling of an individual to faith in Christ. Jesus taught us that this calling of God, this drawing by God the Father, is an effectual calling, meaning that all of those who receive this inward calling will indeed come to Him, and they will all be raised up at the last day. Without this effectual calling of God, the mind of sinful man, which is hostile toward God, has no desire to come to Christ and has not even the ability to come to Him (again, Romans 8:7).

If anyone rejects the Gospel of Christ, it is only because they have never been drawn by the Father; they have never received this inward, effectual calling of God which Jesus spoke about in John 6:44. Believing in Christ is not something that sinful, unregenerate man has the ability or capacity to do, in and of himself, in order to obtain salvation for himself. He must be drawn by the Father. When a man is drawn to Christ by the Father, he is regenerated. He is born into the kingdom of God, and evidence of this regeneration and conversion which God has wrought within him is that he does indeed believe in Christ. Man does not reject the inward calling of God. Rather when the Father draws a man, Jesus will raise him up at the last day, just as He said He would.
