The mercy of God. Another important aspect of the goodness and love of God is His mercy or tender compassion. The Hebrew word most generally used for this is chesed. There is another word, however, which expresses a deep and tender compassion, namely, the word racham, which is beautifully rendered by “tender mercy” in our English Bible. The Septuagint and the New Testament employ the Greek word eleos to designate the mercy of God. If the grace of God contemplates man as guilty before God, and therefore in need of forgiveness, the mercy of God contemplates him as one who is bearing the consequences of sin, who is in a pitiable condition, and who therefore needs divine help. It may be defined as the goodness or love of God shown to those who are in misery or distress, irrespective of their deserts. In His mercy God reveals Himself as a compassionate God, who pities those who are in misery and is ever ready to relieve their distress. This mercy is bountiful, Deut. 5:10; Ps. 57:10; 86:5, and the poets of Israel delighted to sing of it as enduring forever, I Chron. 16:34; II Chron. 7:6; Ps. 136; Ezra 3:11. In the New Testament it is often mentioned alongside of the grace of God, especially in salutations, I Tim. 1:2; II Tim. 1:1; Titus 1:4. We are told repeatedly that it is shown to them that fear God, Ex. 20:2; Deut. 7:9; Ps. 86:5; Luke 1:50. This does not mean, however, that it is limited to them, though they enjoy it in a special measure. God’s tender mercies are over all His works, Ps. 145:9, and even those who do not fear Him share in them, Ezek. 18:23,32; 33:11; Luke 6:35,36. The mercy of God may not be represented as opposed to His justice. It is exercised only in harmony with the strictest justice of God, in view of the merits of Jesus Christ. Other terms used for it in the Bible are “pity,” “compassion,” and “lovingkindness.”
