Is anything too hard for the Lord? (14). We need to hear these words as God’s call to greater faith. Sarah, like Abraham, had heard God’s promises, yet ‘she laughed to herself’(12). We can hear God’s Word, and still remain, in our hearts, men and women of unbelief. The Word of God does not benefit us when we do not receive it with faith (Hebrews 4:2). God knows what is in our hearts, just as He knew what was in Sarah’s heart (13-15). He knows the human heart, ‘deceitful above all things’(Jeremiah 17:9), yet He continues to love us. He does not give up on us. He perseveres with us. He could have given up on Sarah as a hopeless waste of His time, but He did not. ‘The evil heart of unbelief’ is always with us, but God is constantly at work to create in us ‘a clean heart’( Hebrews 3:12: Psalm 51:10). ‘Soften my heart, Lord’(Mission Praise, 606).
In the face of the threatened judgment of God upon Sodom and Gomorrah, we find Abraham engaging in mighty intercessory prayer. He is not concerned only about himself and his own salvation. He is prayerfully committed to seeking the salvation of others. This is a mark of spiritual maturity – a deep concern for the salvation of sinners, leading to earnest intercessory prayer for them. Abraham drew near to God (23; James 4:8). He pleaded with the God of grace to have mercy on the city (23-25; 2 Peter 3:9; 1 Timothy 2:3-4, 1:15; John 3:17). With a deep love for the people, Abraham prays with boldness and persistence (27,32; Hebrews 4:16). A great many people refused to honour God, yet His purpose was not hindered. The remnant seemed impossibly small. It was the beginning of blessing for all nations. ‘To God be the glory, Great things He has done’(Church Hymnary, 374).
