ah, but it does...
Hebrews 1:1 God, who long ago spoke on many occasions and in many ways to our forefathers by means of the prophets, 2 has at the end of these days spoken to us by means of a Son, whom he appointed heir of all things, ....and after he had made a purification for our sins he sat down on the right hand of the Majesty in lofty places
Hebrews 10:12 But this [man] offered one sacrifice for sins perpetually and sat down at the right hand of God, 13 from then on awaiting until his enemies should be placed as a stool for his feet
Acts 7:55 But he, being full of holy spirit, gazed into heaven and caught sight of Gods glory and of Jesus standing at Gods right hand
Colossians 3:1 If, however, YOU were raised up with the Christ, go on seeking the things above, where the Christ is seated at the right hand of God
1Peter 3:22 He is at Gods right hand, for he went his way to heaven; and angels and authorities and powers were made subject to him
Jesus will remain in heaven until he has dealt with all of Gods enemies...thats why he said "just a little while longer and the world will behold me no more"
When Christ returns, it will be to deal with Gods enemy Satan...and we will not visibly see that battle....but we will certainly feel its effects. Keep Awake!
