23 And he went up from thence to Beer-sheba. 24 And the Lord appeared unto him the same night, and said, I am the God of Abraham thy father: fear not, for I am with thee, and will bless thee, and multiply thy seed for my servant Abraham’s sake. 25 And he builded an altar there, and called upon the name of the Lord, and pitched his tent there: and there Isaac’s servants digged a well.
Isaac had been exiled and bullied by the citizens of Gerar. First king Abimelech made him move away because he was getting too powerful, then the herdmen fought with him for control of the wells. This was a time when everything in the world was conspiring against him.
It is touching, then, that in this moment of loneliness and frustration, God appeared to Isaac and said “fear not, for I am with thee.” Isaac may have been alone in the world, but he was alone with God, and God would see that he was taken care of. God would support him when no one else would. God would multiply and increase him, in spite of all the world’s opposition.
And so, like his father before him, Isaac built an altar in the open and called upon the name of his God. He threw in with that one, best friend who would see him through thick and thin.
