Galatians:2:20I have been put to death on the cross with Christ; still I am living; no longer I, but Christ is living in me; and that life which I now am living in the flesh I am living by faith, the faith of the Son of God, who in love for me, gave himself up for me. See All...; Romans:4:18-21 Who without reason for hope, in faith went on hoping, so that he became the father of a number of nations, as it had been said, So will your seed be.  And not being feeble in faith though his body seemed to him little better than dead (he being about a hundred years old) and Sarah was no longer able to have children:  Still, he did not give up faith in the undertaking of God, but was made strong by faith, giving glory to God,  And being certain that God was able to keep his word.
See All...; Hebrews:11:1Now faith is the substance of things hoped for, and the sign that the things not seen are true. See All...; 1 Peter:1:6-7 You have cause for great joy in this, though it may have been necessary for you to be troubled for a little time, being tested in all sorts of ways,  So that the true metal of your faith, being of much greater value than gold (which, though it comes to an end, is tested by fire), may come to light in praise and glory and honour, at the revelation of Jesus Christ:
