“I shall not die, but live, and declare the works of the Lord.” – Psalm 118:17

What does the man know about the sea who has only walked on the beach? Get with an old sailor, who has been a dozen times around the world, and often wrecked, and he will interest you. So the much-tried Christian has great wonders to declare, and these are chiefly the works of the Lord; for “they that go down to the sea in ships, that do business in great waters; these see the works of the Lord, and His wonders in the deep.” Tried Christians see how God sustains in trouble, and how He delivers out of it, and they declare His works openly: they cannot help doing so.

“I will praise Thee: for Thou hast heard me, and art become my salvation.” – Psalm 118:21

If you read the chapter further down, you will find that they not only give forth a declaration, but they offer adoration. They are so charmed with what God has done for them, that they laud and magnify the name of the Lord… This done, they make a further dedication of themselves to their delivering God. As the psalmist puts it,

“God is the Lord, which hath shewed us light.” – Psalm 118:27

It was very dark! It was very, very dark! We could not see our hand, much less the hand of God! We were frozen with fear. We thought we were as dead men, laid out for burial; when suddenly the Lord’s face shown in upon us, and all darkness was gone, and we leaped into joyful security, crying “God is the Lord, which hath shewed us light.” God hath showed us light, and we will live to Him for ever and for ever. Oh, you, tried believers, who have, nevertheless, not been given over unto death, who can say, “I shall not die, but live,” present yourselves anew unto your delivering Lord as living sacrifices through Jesus Christ your Lord! Amen. ~ C.H. Spurgeon
