'Assuming' in the Bible

assuming that you have heard of the stewardship of God’s grace that was entrusted to me [to share with you] for your benefit;

If in fact you have [really] heard Him and have been taught by Him, just as truth is in Jesus [revealed in His life and personified in Him],

saying,“To You we give thanks, O Lord God Almighty [the Omnipotent, the Ruler of all], Who are and Who were, because You have taken Your great power and the sovereignty [which is rightly Yours] and have [now] begun to reign.
