Do you have that spirit of faith? Let faith rule in your lives. Without faith, it is impossible to please God. Anyone who wants to come to him must believe that God exists and that he rewards those who sincerely seek him (Heb. 11:6). Having faith, especially to God, pleases Him.
We can read a lot of stories in the Bible in which the characters had faith in the Lord. You can read them in Hebrews 11. You will be inspired by their testimonies when they put their faith. Although it is not really easy, but they persevered and trusted God to work on their lives. It made God happy 'coz he was pleased by the actions of His servant.
We may learn from the lessons in the Bible to completely have faith in the Lord. It takes a lot of patience to have this. You will be complete in the Lord if you just have faith. What our faith rests on is the belief that God is in ultimate control and will indeed keep His promises—whether that happens in this life or the next. Our greatest comfort in sorrow is to know that God is in control (Our Daily Bread).
