God is good and his mercy endures forever. The Gospel is preached to announce to mankind that there is a Saviour for sinners in the person of the Lord Jesus Christ.
Bible Scriptures: KJV
Psalms 107:1-15 “O give thanks unto the Lord, for he is good: for his mercy endureth for ever. 2 Let the redeemed of the Lord say so, whom he hath redeemed from the hand of the enemy; 3 And gathered them out of the lands, from the east, and from the west, from the north, and from the south.4 They wandered in the wilderness in a solitary way; they found no city to dwell in.5 Hungry and thirsty, their soul fainted in them. 6 Then they cried unto the Lord in their trouble, and he delivered them out of their distresses. 7 And he led them forth by the right way, that they might go to a city of habitation.
8 Oh that men would praise the Lord for his goodness, and for his wonderful works to the children of men!9 For he satisfieth the longing soul, and filleth the hungry soul with goodness.10 Such as sit in darkness and in the shadow of death, being bound in affliction and iron;11 Because they rebelled against the words of God, and contemned the counsel of the most High:12 Therefore he brought down their heart with labour; they fell down, and there was none to help.13 Then they cried unto the Lord in their trouble, and he saved them out of their distresses.14 He brought them out of darkness and the shadow of death, and brake their bands in sunder.15 Oh that men would praise the Lord for his goodness, and for his wonderful works to the children of men!”
