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.
God knows everything about everything, yet Christians sometimes act as though He has some debilitating limitations. Once again, the Bible shines the light of truth upon the matter. It reveals that He is great, “and of great power: his understanding is infinite” (Psalm 147:5). In fact, His eyes “are in every place, beholding the evil and the good” (Proverbs 15:3). In other words, there is nothing that escapes the knowledge and attention of God. This includes the good and the bad! The Son of God proclaimed to the church at Thyatira that He knew their works, charity, service, faith, and patience. He too knows about the level of a man’s faith! He knows the content, strength, and reality of that faith. A man can and will fool others and frequently even deceives himself (Jeremiah 17:9), but he has no capacity to mislead God. The Lord knows those who believe and accept His word as the perfect word of God and He is not unrighteous to forget (Hebrews 6:10).
