What does the Bible say about being late or lateness?

 “A good name is better than precious ointment” (Ecclesiastes 7:1). A good name, a good reputation is important for a Christian. This means that we should be known as people of our word, trustworthy and dependable, and not be known as always late, slothful, or unconcerned about others. Our actions as Christians point back at Christ. Do they glorify Him? Do they bring Him honor? “And whatever you do, do it heartily, as to the Lord and not to men” (Colossians 3:23).

For one thing, continual lateness does not express love for others. Forcing others to wait for us time after time is simply rude. Christians are to love one another and love our enemies as well, and “love is not rude” (1 Corinthians 13:5).
