'Shall' in the Bible

in fulfilment of my eager expectation and hope that I shall never have reason to feel ashamed, but that by my perfect freedom of speech Christ will be glorified in me, now as always, either by my life or by my death.

I am convinced of this, and I know that I shall remain, and shall go on working side by side with you all, to promote your progress and joy in the faith;

but trusting, as I do, in the Lord, I believe that I shall myself also come to you before long.
