When speaking of anger, the scripture uses descriptive terms that could equally be applied to the truths concerning fire. In doing so, the Bible makes a connection that can help believers gain a better understanding of the benefits or dangers of anger. According to scripture, anger can be kindled, a term used to describe the starting of a fire (Exodus 4:14; Numbers 11:1; Deuteronomy 32:22; Jeremiah 15:14), either a little (Psalm 2:12) or greatly (Numbers 11:10; 1 Samuel 11:6). The Bible also describes anger as waxing hot (Exodus 32:19), another connection to fire. These similarities are by divine design. As is true concerning fire, anger can be useful and productive, but it can also be destructive and harmful, especially when it gets out of control.
The Bible provides several sources of man’s joy, but each source can in some way be directly traced back to the Lord. In today's passage, Psalm 43:4 describes God as the psalmist's “exceeding joy.” According to Psalm 16:11, there is “fulness of joy” in God’s presence. While the Bible indicates that man’s soul can be joyful in the Lord (Psalm 35:9; Isaiah 61:10), it also associates joy directly to God’s strength (Psalm 21:1). Moreover, God’s word provides a source of joy for the saint (Jeremiah 15:16). In the New Testament, the book of Romans identifies God as the saint’s source of joy, but specifically, this joy comes “through our Lord Jesus Christ” (Romans 5:11). Perhaps men lack the joy of the Lord because they disregard the Lord of their joy.
