As God had mercy on Nineveh, so He has had mercy upon us. It is for us to believe in, and accept His mercy, by accepting Christ.
Think of the character of His mercy.
1. His mercy is great (Num 14:18; Psa 103:11; Psa 145:8). It is great, because the Father is the Source of it; it is great, because of the price it cost before it could reach us, for sin had blocked up the way. The cost was the blood of Christ.
2. His mercy is enduring (1Ch 16:34, 41; 2Ch 5:13; 2Ch 7:3, 6; 2Ch 20:21; Ezr 3:11; Psa 106:1; Psa 107:1; Psa 118:1; Psa 136 (v1 to the end); and Jer 33:11). Having put His hand to the plough, He never looks back.
3. His mercy is plenteous (Psa 86:5, 15; Psa 103:8). He does not dole it out grudgingly, but showers it upon us abundantly.
4. His mercy is tender (Luk 1:78). He has mercy upon us, not as a judge, but as a Father.
5. His mercy is rich, or He is rich in mercy (Eph 2:4). He keeps not the riches of His mercy to Himself, but, like Joseph, who gave of his abundance to his brethren, even so the Lord gives us of His fulness.
6. His mercy is saving (Tts 3:5). We should never have been saved if our salvation had depended upon ourselves; but He held out the sceptre of mercy to us, as Ahasuerus did to Esther.
7. His mercy is abundant (1Pe 1:3). It is not like a brook that dries up in the summer, but like the sea, which is unlimited. His mercy shall be as an attendant to accompany us (Psa 23:6), and as an army to encompass us (Psa 62:10).
