What does the Bible say about watching and praying?

In Mark 13:34-37, Jesus instructs His disciples to watch and pray, emphasizing that they do not know when the master will return. This is not just a command but reflects a spiritual principle of preparedness and reliance on God. By remaining vigilant, believers demonstrate their faith and readiness for Christ’s return. This call to watchfulness serves as a warning against spiritual slumber, urging Christians to stay alert, spiritually engaged, and reliant on the grace that enables their faith and actions.
