Hebrews 2:1-4. God's people have always lived under pressure that tries to drag them away from the Gospel. The writer reminds his hearers that under the Old Covenant there was no escape from punishment for those who rebelled against the ways of God. Under the New Covenant God has provided a way of salvation in Jesus that is free and certain - how foolish we would be to neglect it.
As Jesus rides into Jerusalem those around him fail to understand the significance of the events unfolding around them; only later will it all make sense. So to for us our understanding of God's ways comes not through our own understanding but through God's revelation.
