Tremble at the presence of the Lord

Psalm 114:1-8
The Lord brought Israel out of Egypt, foreign tongue, Judah became God's sanctuary, Israel became his dominion.
The sea looked God fled, the Jordan turned back, tremble, O earth, at the presence of the Lord, at the presence of the God of Jacob.
The God turned the rock into the pool, the hard rock into the spring of water.
Psalmist praised God's leading Israel and his mighty hands.
Why?
This is the festival which marks the escape from Egypt at the exodus. The people remember how God freed them when they were slaves and made them his own people.
Is the Lord who frees his people from the slave to the holy place.
The Lord turned the impossible to the possible. Nothing is impossible to the Lord, Jehovah my God.
How?
Trust in Thee, in Him there is no dark, in Him there is nothing difficult. He is my savior, my redeemer. Tremble before the Lord.
