So Abram departed, as the LORD had spoken unto him; and Lot went with him: and Abram was seventy and five years old when he departed out of Haran.
So Abram departed - primitive and simple-hearted, at an age when he would not be apt to be imposed upon by an illusion of the fancy, but would calmly and deliberately weigh the step he was called to take. Abram, like Paul, was not disobedient to the heavenly vision; and his obedience is frequently mentioned in the New Testament as a striking instance of his faith (Hebrews 11:8). It is not to be supposed that at this stage he knew exactly the purposes for which he was separated, or could clearly distinguish the spiritual from the temporal branches of the Promise (cf. Hebrews 11:9-10). But in the consciousness of supernatural guidance, and with the hope of great, though unknown blessings, he "departed as the Lord had spoken unto him." Believing God (Romans 4:3; Galatians 3:6), he said in his heart:
`Thy call I follow to the land unknown; I trust in Thee, and know in whom I trust; Or life or death is equal-neither weighs: All weight in this-Oh let me live to thee!'
