why did Jesus said only the Father knows the hour?

When Jesus said that only the Father knows the hour of His return (Mark 13:32), He emphasized the mystery and sovereignty of God's plan regarding the end times. This statement highlights the distinction between the roles of the Father and the Son within the Trinity, underscoring Jesus' humility and obedience to the Father's will. It also serves to encourage believers to remain vigilant and prepared, as the exact timing of these events is unknown to humanity.
