Psalm 150:2 (ESV)

2 Praise him for his mighty deeds; praise him according to his excellent greatness!

Mighty are God’s deeds. That already started at creation. God spoke and it happened. Light broke through, and darkness gave way. The water masses were shown their place. Green growth appeared at his command. The heavenly bodies started their trajectories.

The whole earth became habitable for man and animals at his mighty word. Genesis 1:31a relates to us, And God saw everything that he had made, and behold, it was very good.

God’s mighty deeds continued, also after man fell into sin.

The Lord said to Moses, I have surely seen the affliction of my people who are in Egypt and have heard their cry because of their taskmasters. I know their sufferings (Exodus 3:7). The Lord acted and by his mighty arm a path appeared in the Red Sea, and the people reached the other side without getting their feet wet, while Egypt’s army perished in the Red Sea.

Then Moses sang a song in honour of the Lord, I will sing to the LORD, for he has triumphed gloriously; the horse and his rider he has thrown into the sea (Exodus 15:1). And the prophetess Miriam took her tambourine (Exodus 15:21), and while dancing she sang the chorus, Sing to the LORD, for he has triumphed gloriously; the horse and his rider he has thrown into the sea. The song of God’s mighty and redeeming deeds echoes through in many of the psalms (as in Psalm 106:2; Psalm 145:4, Psalm 145:12).

It is impossible not to think here of God’s greatest deed in sending his Son into the world. An angel then (in Luke 2:10–11) says to the astonished shepherds: Fear not, for behold, I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Saviour, who is Christ the Lord. This Saviour therefore shall be called Jesus (Matthew 1:21; Luke 1:31).

In him for now and forever shines God’s mightiest deed for humanity. Through him, God’s saving power has reached its pinnacle. Now we have all the reasons (we need) to praise this mighty and great God abundantly.
