Why is watching and praying important for Christians?

In Mark 13, Jesus instructs His disciples to watch and pray as they await His return, emphasizing that they do not know the day or hour of His coming (Mark 13:33). This admonition serves as a reminder of our human frailty and the need for God's grace to remain steadfast in faith. Watching implies being spiritually alert and ready for Christ's return, while praying fosters reliance on God for strength and perseverance. Moreover, the call to watch and pray reflects a posture of humility and dependence, acknowledging that, apart from God’s grace, we would falter and stray from Him.
