Why is it important that God cannot deny Himself?

The importance of God not being able to deny Himself lies in the assurance it provides to believers regarding their salvation. If God were capable of denying His own nature, it would introduce uncertainty into His promises. However, as the sermon emphasizes, God remains faithful even when our faith falters, echoing 2 Timothy 2:13: 'If we believe not, yet he abideth faithful; he cannot deny himself.' This unchanging faithfulness gives believers confidence in their assurance of salvation, knowing it rests solely on God's immutable character.
