New Defender's Study Bible Notes
20:26 the doors being shut. Even though Christ’s resurrection body was a physical body (He could be touched, still had the wounds, and could eat with them), it was no longer subject to the physical constraints on our present bodies (e.g., gravitational forces, electromagnetic forces). For example, He could pass through locked doors, and travel swiftly from earth to heaven and back. Our future resurrection bodies will be like His in such characteristics (Philippians 3:20-21; I John 3:2).
