Genesis 18:24
Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein? Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein?
The opening plea asks that Sodom be spared if fifty righteous are found within it, rather than destroying the righteous together with the wicked. It appeals to God as the Judge of all the earth who does what is right and does not sweep away the righteous with the guilty.
The plea is an intercession for sinners that reveals willingness on God's part to spare a whole place for the sake of the righteous in it. The righteous who love and fear Him are a reason for extending mercy and holding back judgment from where they live.
It was moved by concern for Lot and for the city, so the asking was pressed again and again until assurance was given that the city would be spared if even ten righteous were found there. In the end only ten honest people could be found, and Sodom was destroyed after licentiousness had spread through it.
The prayer was offered in reverence and humility, as a sinner seeking mercy for others rather than from confidence in personal righteousness. It revealed a benevolent, noble and compassionate character, shown in earnest pleading for the people of Sodom. That love was directed toward perishing people whose sin was hated while their salvation was desired.
In this setting Abraham stood as God's representative to reveal the God of heaven to the inhabitants of Sodom. He did not shut himself away but maintained friendly relations with the kings of the surrounding nations, by some of whom he was treated with great respect. His fidelity was a light to the people in all the countries of his sojourn, in Mesopotamia, in Canaan, in Egypt, and even to Sodom, as his integrity and unselfishness and his valor and benevolence represented the character of God.
The verse models how faith leads to concern for the erring and willingness to plead for their good. It calls others to share that concern for the impenitent by warning them and pleading with God for them before their time of mercy ends.
As part of the Genesis 18-19 message, it calls hearers to seek the Lord most earnestly and take a more decided stand. They are to be not merely professed believers in the truth but obedient to all of God's requirements, with confession, earnest prayer, and hearts softened and subdued under the touching power of the Spirit.
