"And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day; And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground, And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:" (Genesis 18:1-3)
Here is something interesting I learned in my husband's sermon tonight. When you see 'LORD' written in large text in some Bibles (here in the KJV), it is a Hebrew word for Jehovah. But notice in verse 3 there is another word, 'Lord' with a capital letter and lower case letters for the rest of the word. This second is the Hebrew word, 'Adonay'. One may think here, that Abraham didn't realize this was God in a fleshly form, but the term 'Adonay' is only used with God. How did Abraham know this was 'Adonay'?
This could be an interesting study for someone wanting to dig deeper!
Simply a Christian. "Be imitators of me, as I am of Christ." (1 Corinthians 11:1) "Therefore encourage one another and build one another up, just as you are doing." (1 Thessalonians 5:11)
