Another of the famous “I am” sayings of Jesus (see on ch. 6:35; see chs. 8:12; 10:7, 11; 11:25). For the use of the expression “I am” without the pronoun “he” see on ch. 8:24.
Christ is the way from earth to heaven. By His humanity He touches this earth, and by His divinity He touches heaven. He is the ladder connecting earth and heaven (ch. 1:51; cf. PP 184). Because of His incarnation and death “a new and living way” has been consecrated for us (Heb. 10:20). There is no other means of salvation (Acts 4:12; 1 Tim. 2:5).
