Jesus told Nicodemus heavenly things (Jn 3:12). "'No one has ascended into heaven, but He who descended from heaven: the Son of Man'" (:13). Jesus knew "that He had come forth from God, and was going back to God" (13:3). "For the joy set before Him [he] endured the cross, despising the shame" (Heb 12:2). "Through the resurrection of Jesus Christ" (1Pe 3:21) "He had made purification of sins" (Heb 1:3) so we could have "clean hands and a pure heart" (Ps 24:4) and "may stand in His holy place" (:3). "'Was it not necessary for the Christ to suffer these things and to enter into His glory?'" (Lk 24:26). Jesus told them, "'But now I am going to Him who sent He'" (Jn 16:5). "He sat down at the right hand of the Majesty on high" (Heb 1:3) and "at the right hand of the throne of God" (12:2). There he "intercedes for us" (Ro 8:34). God "seated Him at His right hand in the heavenly places" (Eph 1:20) and "bestowed on Him the name which is above every name" (Php 2:9). "You are the Lord Most High over all the earth; You are exalted far above all gods" (Ps 97:9). God then told him to "'sit at My right hand until I make Your enemies a footstool for Your feet'" (110:1).
John reports that, "'After these things I looked, and behold, a door standing open in heaven'" (Rev 4:1). Ezekiel said that "the heavens were opened and I saw visions of God" (Ez 1:1). When Jesus was baptized "the heavens were opened, and he saw the Spirit of God descending as a dove and lighting on Him" (Mt 3:16). Stephen said, "'I see the heavens opened up and the Son of Man standing at the right hand of God'" (Ac 7:56). In John's case a voice directed him to, "'Come up here, and I will show you what must take place'" (Rev 4:1). He saw that "'a throne was standing in heaven, and One sitting on the throne'" (:2). Isaiah said, "In the year of King Uzziah's death I saw the Lord sitting on a throne, lofty and exalted: (Isa 6:1). Ezekiel stated that "in the expanse that was over the heads of the cherubim something like a sapphire stone, in appearance resembling a throne, appeared above them" (Ez 10:1). John says, "'He who was sitting was like a jasper stone and a sardis in appearance, and there was a rainbow around the throne'" (Rev 4:3).
Jesus "led them out as far as Bethany, and He lifted up His hands and blessed them" (Lk 24:50). "After He said these things, He was lifted up while they were looking on, and a cloud received Him out of their sight" (Ac 1:9). "He was received up into heaven and sat down at the right hand of God" (Mk 16:19). "As they were gazing intently into the sky while He was going, behold, two men in white clothing stood beside them" (Ac 1:10). They said that Jesus would return "'in just the same way as you have watched Him go into heaven'" (:11). "You have ascended on high, You have led captive Your captives" (Ps 68:18). "When He had disarmed the rulers and authorities, He made a public display of them, having triumphed over them through Him" (Col 2:15). "'He gave gifts to men'" (Eph 4:8). "To each one of us grace was given according to the measure of Christ's gift" (:7).
