"Psalm 118:
It seems reasonable to propose that Moses possibly wrote this beautiful psalm to look back in worship at the historical Passover and look ahead in wonder to the spiritual Passover in Christ.
I. Call to Worship (118:1-4);
II. Personal Praise (118:5-21);
III. Corporate Praise (118:22-24);
IV. Commitment to Worship (118:25-29).
Psalm 118:1 O give thanks unto the LORD; for [He is] good:because His mercy [endureth] for ever.
Psalm 118:6 The LORD [is] on my side; I will not fear: what can man do unto me?
Psalm 118:8 [It is] better to trust in the LORD than to put confidence in man.
Psalm 118:9 [It is] better to trust in the LORD than to put confidence in princes."
