Jesus answered them, "This is the work of God, that you believe in him whom he has sent."
      [1.] That the Son will bid all those welcome that come to him (John 6:37):  Him that cometh to me I will in no wise cast out.  How welcome should this word be to our souls which bids us welcome to Christ!  Him  that cometh; it is in the singular number, denoting favour, not only to the body of believers in general, but to every particular soul that applies itself to Christ. Here,  First,  The duty required is a pure gospel duty: to  come to Christ,  that we may come to God by him. His beauty and love, those great attractives, must  draw  us to him; sense of need and fear of danger must  drive  us to him; any thing to bring us to Christ.  Secondly,  The promise is a pure gospel promise:  I will in no wise cast out—ou me ekbago exo. There are two negatives:  I will not, no, I will not.  1. Much favour is expressed here. We have reason to fear that he should  cast us out.  Considering our meanness, our vileness, our unworthiness to come, our weakness in coming, we may justly expect that he should frown upon us, and shut his doors against us; but he obviates these fears with this assurance, he  will not  do it; will not disdain us though we are mean, will not reject us though we are sinful. Do poor scholars come to him to be taught? Though they be dull and slow, he will notcast them out.  Do poor  patients  come to him to be  cured,  poor  clients  come to him to be  advised?  Though their case be bad, and though they come empty-handed, he will  in no wise cast them out.  But, 2. More favour is implied than is expressed; when it is said that he will no cast them out the meaning is, He will receive them, and entertain them, and give them all that which they come to him for. As he will not refuse them at their first coming, so he will not afterwards, upon every displeasure, cast them out.  His gifts and callings are without repentance.
