Coming to Jesus
John 6:37 (ESV) … “All that the Father gives me will come to me, and whoever comes to me I will never cast out.”
In the Greek, the words all that are neuter singular, indicating the total body of believers for all time. The Father gives this collective group to the Son (see also 17:2, 24). Only those selected by God can come to the Son and believe in him. God’s Spirit enables them to come. All those who have been invited to come to Jesus and have done so can rest assured that God was at work in their lives.
“The one who comes to Me I will by no means cast out.” While the first part of this verse speaks of the collective group of believers, this second part speaks about the individual. God’s Word assures us that Jesus will always welcome the sincere seeker, and the seeker who comes to believe will never be rejected (10:28–29).
OUR PLACE IN THE PLAN
The Father gives, the Son preserves, and we come. God’s foreknowledge is a part of his character that we must accept though we do not fully understand. We must ask ourselves: Am I one of those who has come to Christ? Whether or not we are among those whom the Father has given to the Son, or whether we are secure in Christ’s protection, depends on how we answered the first question—have we come? When we come to Jesus, we find great assurance in his promise that we will never be rejected.
