Without becoming weak in faith [Abraham] contemplated his own body, now as good as dead since he was about a hundred years old, and the deadness of Sarah’s womb; yet, with respect to the promise of God, he did not waver in unbelief but grew strong in faith, giving glory to God, and being fully assured that what God had promised, He was able also to perform.
When you act in faith, you give the glory to God for the outcome!
Abraham “did not waver in unbelief but grew strong in faith, giving glory to God”. Abraham knew that what God had promised was impossible for men, but he chose to believe God, and in expressing his faith, he constantly gave God the glory for what He did.
When you are truly acting in faith, you will not go around parading the greatness of your faith and looking for the praise of others. Rather, you will be so completely aware that it was God who did it that you will look for any way possible to glorify Him and downplay yourself.
When you share with others about what the Lord has done in your life, God is watching to see if you honor Him or yourself in the way that you share it. He wants you to share about what He is doing for you, and when you do, be sure your words point people to Him.
