Because of acts of disobedience in the heavenlies and on the earth there exists at this time a gulf between God and mankind. This is not to say that Christians cannot and do not communicate with God and His Son Jesus since "our fellowship is with the Father, and with His Son Jesus Christ (1 John 1:3). But there does not exist and will not exist the intimacy in communication between us and the Creator like there was in Eden until the gulf is bridged. According to the John the Revelator this will occur when there is "no more Sea" (Revelation 21:1). What "sea" is this you ask? That question deserves a detailed answer.
Jesus did a majority of the work to mend the rift by his life, death, resurrection, ascension and his seating at the "right hand of the Father", but there's more work to be done, by him and his Father. This website is dedicated to this truth.
