'Presence' in the Bible

Now to whomever you forgive anything, I also [do]; for indeed, whatever I have forgiven, if I have forgiven anything, [it is] {for your sake} in the presence of Christ,

because it is said, "His letters [are] severe and powerful, but his bodily presence [is] weak and his speech is of no account."

[I am afraid] lest [when I] come again my God will humiliate me {in your presence}, and I will grieve over many of those who sinned previously and have not repented because of their impurity and sexual immorality and licentiousness that they have practiced.
