Biblical prophets and saints of old had access to spiritual portals to communicate with Yahweh and transport from one location to another as the spirit moved them. You have the ability to transport from the center of your mind to the Holy of Holies in heaven. Christ is the portal, and he is in us. This means the portal of heaven is inside of us. "Yahweh is in his holy temple, Yahweh's throne is in heaven" (Psalms 11:4). You are the temple of God and his spirit is dwells in you (1Corinthians 3:16, & 6:19). God is in you (his temple) on the throne inside of you. His throne is in heaven and this means heaven is within you. Christ said, "The kingdom of God is inside of you" (Luke 17:21). We are in God and he is in us. "In him we live, and move, and have our being" (Acts 17:28). If you are willing to make some changes and to dedicate some effort and time, the proper forms of meditation will carry you to wonderful places heretofore unknown by you. All you need to do is open the door.
