How do we know that Christ will keep His people?

The assurance that Christ will keep His people is rooted in His promise found in John 14:2-3, where He declares, 'In my Father's house are many mansions... I go to prepare a place for you.' This promise signifies that He is actively working for the benefit of His people. His intercession for us is also a powerful testimony to His commitment to our perseverance, as seen in His words to Peter: 'I have prayed for you, that your faith may not fail' (Luke 22:32). Thus, the faithfulness of Christ ensures that all whom He has chosen and saved will be kept until the end.
