Most of us would assume that the Lord laughed at some point during His earthly ministry, yet the scripture never focuses on this point. Rather, the scripture seems to focus on the fact that He was “a man of sorrows, and acquainted with grief” (Isaiah 53:3). We know very little of any laughter, yet we do know that He wept at the tomb of Lazarus (John 11:35). He further lamented over Jerusalem because of their rebellion (Luke 13:34). We also know that He sighed at the healing of the deaf man who had a speech impediment (Mark 7:34). Heaven affords the Lord great rejoicing, yet His earthly ministry was consumed by heartache rather than mirth. This most likely was a result of dealing with the consequences of man’s sin.
Believers should be zealous of good works, but their zeal must not spring from a position of ignorance. The Bible points to the Jews as a zealous people, but their zeal was not according to knowledge. Nobody worked harder trying to reach a righteous state than did the Jews. However, they failed to realize that true righteousness comes as an unmerited gift from God. Yet, the Jews were “ignorant of God's righteousness,” and went “about to establish their own righteousness” (Romans 10:3). Paul repeatedly testified concerning the futility of trying to earn God's favour through one’s own efforts (Acts 22:3; Philippians 3:6). Before Paul came to know Christ, he thought he should fight against Christ’s followers and zealously persecute the church of God. He even placed many of the new believers into prison and caused their deaths. Yet, he declared that all this was done in ignorance (1 Timothy 1:13). He, like the Jews, had a tremendous zeal, but that zeal was not according to knowledge.
