What does the Bible say about being ready for Christ's return?

Matthew 24:42-44 instructs believers to be watchful and prepared because the exact time of Christ's return is unknown. This passage serves as a warning to always be ready, as the Lord will come back unexpectedly, akin to a thief in the night. Preparation involves constant prayer and a focus on Christ, ensuring that we are living in a manner that aligns with His will. The importance of being ready is further underscored by the examples of Noah and Simeon, who were both watchful and prepared for God's actions.
