Genesis 21 starts out by saying that the Lord visited Sarah as he said he would and did unto Sarah as he had spoken. This establishes the fact that you can take the Lord at his word. He shows up (visits) as he promises and does what he says he would do.

Jesus showed up at the appointed time (Galatians 4:4) as God had promised (prophesied) in the garden of Eden (Genesis 3:15) and did the will of God the Father (John 6:38). However the people did not know the time of the Lord’s visitation which grieved the heart of Jesus, so much so, that he wept over Jerusalem (Luke 19:41-44). Jesus has also promised to return again and visit mankind just as he had done in the past (John 14:3).

Points to ponder:
God shows up as he promises and does what he says he will do. He said that he will come back to take those who believe in him to where he is (John 14:1-3) and you can take him at his word. The LORD’s visitation is a surety. The question is whether we will be ready or not to know of his vistation? Failure to recognize his visitation grieves the very heart of God. Would you have Jesus cry again? Watch and be on guard for the Lord’s visitation, for he has promised it.

Genesis 21:1 (KJV)
1 And the Lord visited Sarah as he had said, and the Lord did unto Sarah as he had spoken.

Luke 19:41-44 (KJV)
41 And when he was come near, he beheld the city, and wept over it,
42 Saying, If thou hadst known, even thou, at least in this thy day, the things which belong unto thy peace! but now they are hid from thine eyes.
43 For the days shall come upon thee, that thine enemies shall cast a trench about thee, and compass thee round, and keep thee in on every side,
44 And shall lay thee even with the ground, and thy children within thee; and they shall not leave in thee one stone upon another; because thou knewest not the time of thy visitation.
