Promises are only as good as the one who makes the promise. A politician’s promise is worth about as much as a Zimbabwean $1,000,000,000,000 bill (perhaps an insult to Zimbabwe’s currency). You should be rightly incredulous if you get an email promising they’ll wire you a share of a Thai prince’s inheritance, if you provide your bank account number.
The word of promise is reliable or suspect all depending on the nature of the Promiser. Baptism is a promise, but Who is promising in this sign of baptism? The One who is promising salvation by grace through faith to this child is the King of Israel. His nature is not fickle; His character doesn’t ebb & flow; His purpose doesn’t change with fads; His will isn’t determined by public opinion polls. As Solomon once prayed, “there hath not failed one word of all his good promise, which he promised by the hand of Moses his servant (1 Kng. 8:56).”
He spoke light into being, and it was. He promised a Seed to Eve, and after many years, He was born in Bethlehem. He promised that He’d die & rise again, and He arose triumphant. Christ the Promiser now promises to these parents & their child, “All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out (Jn. 6:37).”
So welcome covenant child to Jesus Christ…
