To “sit tight” can mean to actually remain sitting, or it can mean to remain in the location where you are.
As for the phrase “the right hand of the Father,” we must remember that in Scripture the “right hand” is a reoccurring image. It generally denotes closeness (Ps. 16:8), possession (Ps. 78:54), authority (Ps. 110:1), honor (Ps. 45:9), or power (Ps. 60:5, 118:16).
