This is the first time this phrase is used - the word was to come in various ways (Hebrews 1:1 ), and in the Word Himself. The word to Abram (Genesis 15:1 ) was appropriate to his need. He needed God as his shield from any avenging plot of the kings he had defeated (Genesis 14 ). He needed reward having turned down the worldly king of Sodom. The child of God need fear nothing except to offend the Lord.
Abram's question showed his attention was on his problem, "childless", not on God's promises. God tells him he is to have an heir of his own body (Genesis 15:4 ), that his descendants would be as numberless as the stars. (Genesis 15:5 ).
Verse 6 teaches Abram's justification by faith. He did not just believe the Lord, he believed IN the Lord to perform. He believed the fact that he would have a son - he acted upon that faith and gave himself to God. He believed in the multiplication that would result.
He believed in the Lord for his righteousness and it was accounted to him by the Lord (Genesis 15:6; Romans 4:16-25 ). Abram was justified in believing what he heard (Galatians 3:5, 6 ). Abram's faith was a living faith issuing in devoted obedience (James 2:23 ).
In response to the question 'How shall I know that I shall inherit it (the land)?', (Genesis 15:7, 8 ), he is told to bring the offering for the covenant sacrifice (Genesis 15:9 ). The making of a covenant required the cutting of the sacrificial animals into two (Genesis 15:10 ), then the parties of the covenant solemnly walked between the two parts (See Jeremiah 34:18 ). God made solemn covenant requiring Abram's seed inheriting the land, solemnising it by "a smoking oven and a burning torch that passed between those pieces" (Genesis 15:17 ). The covenant included from the river of Egypt to the river Euphrates (Genesis 15:18-21 ). A prophecy of the Israelites sojourn in Egypt that was to last 400 years (Genesis 15:13-14 ). But nothing would stop the fulfilment of God's covenant promise.
Her suggestion was in accord with the practice of the day (Genesis 16:1-3 ).
When in the flesh attempt is made to help God fulfil a promise, trouble ensues. Hagar's pregnancy caused her to adopt a superior air towards her mistress - Sarai grew angry and ill-treated her, and Hagar ran away (Genesis 16:4-6 ).
Wandering in the wilderness she was met by the angel of the Lord who made promises for her and her child and sent her back to Sarai (Genesis 16:7-14 ). What a revelation Hagar received. "You-are-the-God-who-sees." Genesis 16:13.
When Abram was 86 Hagar bore Ishmael, meaning 'God hears.' Hagar and her child are the picture of the old covenant, made at Sinai, the members of which are in bondage (Galatians 4:21-27 ). Abram's mistake was to cost Israel dearly. We are not the children of the old; in bondage, but, the New Jerusalem in heaven, the place where God lives, who adopts us into His family - where we enjoy freedom in Christ.
