(Abraham) lifted up his eyes and looked, and behold, three men were standing in front of him.
Unexpected visitors can cause panic or joy according to who they are! Panic maybe because the catch you unprepared, joy when it is great friends whom you haven't see for ages.
Abraham may well have been having a rest in the shade of his tent when he became aware of three visitors, one of whom he immediately understood was none other than the Lord himself — one of those rare appearances of the Son of God, Jesus, in the Old Testament. Like the perfect host of those times Abraham saw that food was prepared for his visitors, and water to wash their feet.
This visit of the Lord and two angels had a very serious purpose. God was going to destroy Sodom and Gomorrah because of the wickedness of these cities. Abraham's nephew Lot lived in Sodom. The Lord told Abraham what was going to happen to Sodom and Abraham began to plead with the Lord to save the city, or at least to save Lot and his family and any other good people. The Lord agreed to Abraham's request — an amazing instance of the grace of God and of Abraham's boldness in praying — and the two angels rescued Lot and his family. There were no other people in the city who loved God.
Do you have friends and people you love who are not yet Christians? Pray to God for their conversion.
Dear Lord, I pray that you will save my unconverted friends. Please be merciful to them. Amen.
