Hope sustains us today. But Hope will culminate in sight when He comes again. All will be right when He returns if we are found faithful to Him. The Christian experiences a metamorphosis into the beautiful image of Christ. It does not happen all at once, but gradually.
Salvation is the message of the Bible from beginning to end.
God is the God of our salvation. In the Old Testament it takes a physical form. First as salvation from Egyptian captivity, then salvation from sundry enemies, then salvation from Babylonian captivity, or in the Psalms and in Job as salvation from personal troubles. In the New Testament, salvation becomes salvation from sin and its punishment. A special word was on the lips of First Century Christians.
