The Days of Unleavened Bread picture a new way of life that we must walk in. We are to worship God as He commanded. We can't neglect our relationship with God or we can fall into the same attitude as the Israelites.
Matthew 4:4
Hebrews 2:1-3
Hebrews 11:8
Sometimes God simply says "walk this way". We don't always know where we're going,
2 Corinthians 5:1-7
Walk by faith, not by sight.
