Genesis 28:18-22

Jacob set the stone up as a memorial to this revelation and God’s promise (Genesis 28:18). Pouring oil on it constituted an act of consecration. Jacob did not build an altar in response to God’s revelation, as his forefathers had done.

Jacob vowed to convert his pillar into an altar if God would fulfill His promise (Genesis 28:15). This is the only recorded time that a patriarch proposed a vow with God (cf. Genesis 31:13). He swore that Yahweh would be his God if God proved faithful to him. Jacob’s vow (Genesis 28:20-21; cf. Genesis 31:13; Genesis 35:1-3; Genesis 35:7) can be translated "Since . . . " rather than "If . . . " This was probably not as crass a bargain as it appears to have been, though the record of Jacob’s life shows that he typically was keen on negotiating deals. Jacob was apparently a believer in Yahweh already, but his commitment to God at this time appears to have been somewhat selfish and conditional. He had not yet fully surrendered and dedicated himself to God. [Note: On tithing, see the note on 14:20.]

"The assurance of God’s presence should bring about in every believer the same response of worship and confidence it prompted in Jacob. This is the message from the beginning: God by grace visits His people and promises them protection and provision so that they might be a blessing to others. They in turn were to respond in faith, fearing Him, worshiping Him, offering to Him, vowing to Him, and making memorials for future worshipers at such places." [Note: Ross, "Genesis," p. 75.]

Jacob’s relationship with Yahweh was quite different from what Abraham or Isaac’s relationship had been. God tested Abraham, but Jacob tested God. God told Abraham to leave his country before he entered into blessing, but Jacob imposed conditions on God before he vowed to bless God. [Note: J. H. Walton, Genesis: The NIV Appication Commentary, pp. 573-74.] He was willing to accept God’s promises, but he did not commit himself to God until God proved faithful to him personally. God blessed Jacob because of God’s election and Abraham and Isaac’s faith more than because of Jacob’s faith at this time.

Many believers bargain with God as Jacob did here. They agree to worship Him on their terms rather than because God has proven Himself faithful in the past. God often accommodates such weak faith, but the fact that He does does not commend the practice of bargaining with God.

The revelation of God’s presence and promised blessings inspires genuine worship. This worship is the appropriate response to such revelation.
