There’s a profound irony at play here. God is letting us in on a divine joke. To earthly perception an infant presented for baptism has a full life before them. It would seem like death is far off. Yet this sign joins us to death. Of course, not just any death, but Christ’s death.
If you aren’t joined to this death, the death of Christ, you shall remain joined––no matter how long your life is––to Adam’s death. Life outside of being bound to Christ’s death, is dying even while you live. Yet by dying here, this saint is promised life forevermore.
The divine joke in baptism is that by surrendering our life to Christ’s death, we receive His life & are delivered from eternal death. Indeed, in our baptism those words of Christ ring loud and clear: whoever would save his life will lose it, but whoever loses his life shall gain it.
So welcome our sister/brother to Jesus Christ…
