When I was a child, I used to sing the song by Kay Chance, relatively more often than now. The song is entitled, “Ah, Lord God” and the words are taken from the Jeremiah 32:17. The lyrics go as:

Ah Lord God, Thou hast made the heavens And the earth by Thy great power;
Ah Lord God, Thou hast made the heavens  And the earth by Thine outstretched arm.
Nothing is too difficult for Thee, Nothing is too difficult for Thee;
O, great and mighty God,  Great in power and mighty in deed,
Nothing, nothing, absolutely nothing, Nothing is too difficult for Thee.

These words that were given through prophet Jeremiah, are indeed the answer to the question that the Lord posed to Abraham and Sarah, when he asked them (and through them – us) “Is anything too hard for the Lord?” (Genesis 18:14).

Jesus takes this one step further and makes it evidently clear by not just his words (Luke 18:27), but his works of making the blind see (Mark 8:22-25), the deaf hear (Matthew 7:31-37), the mute speak (Matthew 7:31-37), the lame walk (John 5:1-13) and the dead rise (Matthew 11:1-5; John 11:1-45), expressing that not only is nothing too hard for the Lord, but that there is nothing that is impossible for God.

Points to ponder:
Question: Is there anything too hard for the Lord?
Answer: Nothing, nothing, absolutely nothing.
Explanation: The things which are impossible with men are possible with God (Luke 18:27)

Genesis 18:14 (KJV)
14 Is any thing too hard for the Lord? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

Jeremiah 32:17 (KJV)
17 Ah Lord God! behold, thou hast made the heaven and the earth by thy great power and stretched out arm, and there is nothing too hard for thee:

Luke 18:27 (KJV)
27 And he said, The things which are impossible with men are possible with God.
