20 Our God is a God of salvation,
and to GOD, the Lord, belong deliverances from death.
21 But God will strike the heads of his enemies,
the hairy crown of him who walks in his guilty ways.
22 The Lord said, "I will bring them back from Bashan,
I will bring them back from the depths of the sea,
23 that you may strike your feet in their blood,
that the tongues of your dogs may have their portion from the foe."
God's salvation is no small thing. It costs far more than we often think.
It cost Jesus His comfort in Heaven and His taking upon Himself human flesh and limiting Himself to our time and geography. A boundless God stepped in a small town in Israel. A timeless LORD became a baby.
It also costs the lives of those who oppose this LORD and His salvation.
It may be taboo, but it is undeniable with even a cursory glance through Scripture. Even Psalm 23, the staple of comfort for Christians in times of despair, mentions that our enemies will watch us reclining in rest (however they are not invited to the feast).
Even the great Psalm 139 which is often quoted on pillows and baby blankets showing that God knit us together in the womb ends on a very ominous tone.
The LORD is just and sin will require payment in full: either in Jesus' cross or by the individual who committed them.
