Jesus said, I am the resurrection and the life - “The whole power to restore, impart, and maintain life, resides in Me.” (See on Joh 1:4; see on Joh 5:21). What higher claim to supreme divinity than this grand saying can be conceived?
he that believeth in me, though ... dead ... shall he live - that is, The believer’s death shall be swallowed up in life, and his life shall never sink into death. As death comes by sin, it is His to dissolve it; and as life flows through His righteousness, it is His to communicate and eternally maintain it (Rom 5:21). The temporary separation of soul and body is here regarded as not even interrupting, much less impairing, the new and everlasting life imparted by Jesus to His believing people.
