COMMENTARY

And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise
We have spent some time examining the covenant blessings, which we noted were given through Abraham to all his generations. To inherit eternal life we must come through that same covenant lineage, which is made possible to all of us by being adopted through Jesus Christ.

For as many of you as have been baptized into Christ have put on Christ
Being adopted through Jesus Christ requires being baptized into him. Thus all that have this baptism will, by default, inherit the blessings of Abraham.

And Jesus said unto them, Ye shall indeed drink of the cup that I drink of; and with the baptism that I am baptized withal shall ye be baptized:
Note that this is not just any baptism, though. Language like “baptized into Christ” and “the baptism that I am baptized with” seem to suggest that we are supposed to have the same experience with our baptism that he did. And what exactly was that baptism experience?

And the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him: And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.
Jesus, it turns out, was a direct descendant of Abraham. Therefore he already had all of the same covenant promises by default. But God is not a God of “by default.” When Jesus was baptized it was accompanied by a personal declaration of divine approval.
This is the baptism experience Jesus intends for us. Not some impersonal wetting and an assumption of blessings received, but rather a direct and personal affirmation from God Himself.
If you have already been baptized and it lacked this sort of grandeur, don’t feel bad. That was my situation as well, but I learned that this moment of affirmation will still come. It will come, but only when you are ready and the time is right.
