The Daily Meditaiton - Romans 4:16, 20-21

16 Therefore it is by faith, that it might come by
grace, and the promise might be sure to all the seed,
not to that only which is of the Law: but also to that
which is of the faith of Abraham who is the father
of us all,
20 Neither did he doubt of the promise of God
through unbelief, but was strengthened in the faith,
and gave glory to God,
21 Being fully assured that he which had promised,
was also able to do it. (a)

(a) Editor’s thought - The key here is that we believe in God through our faith in Him. We have never seen God physically, but we KNOW, through faith that He IS!
