The only way to please God is by faith. Faith sees Him who is invisible to the eyes of man. Faith prays and receives from God. Faith enables you to walk with God in daily fellowship. You can never please God without faith. "But without faith it is impossible to please Him" (Hebrews 11:6).
You may say, "I try to have faith, but doubt hinders me." Doubt is a call for you to beware of the subject of faith. You may try to have faith in your faith. Faith can never be self-centered. Faith must be focused upon the only one who can give faith. "Looking unto Jesus, the author and finisher of our faith" (Hebrews 12:2).
Faith comes to you only through Jesus Christ as a gift of the Holy Spirit. Trying to have faith any other way simply will not work. A man came to Jesus seeking help, but he had trouble believing. He said, "Lord, I believe; help my unbelief" (Mark 9:24). Jesus still helps people with doubt and unbelief. Look unto Jesus for your faith. He will freely give you faith without doubt.
Faith without doubt comes to you by grace alone. Grace is God's gift in Christ. Grace gives you all the faith you will ever need. Look not to yourself, nor to any other, but the Lord Himself. Grace brings faith from the source of all faith. What God expects from you, He provides for you, even faith without doubt.
