Dedication to God can be explained to mean complete loyalty or commitment to God, which transcends the immediate gratification or expectation of any physical reward. The willingness to trust and put faith in God, and surrender to His instructions is a step that is pleasing to God, "And without faith it is impossible to please God, because anyone who comes to him must believe that he exists" (Hebrews 11:6).
Therefore, every believer needs to reach the height of unshakable trust and reliance on God's words as being reliable in the past, the present and in the future. Such trust and reliance on God and His word is evidence that genuine faith and firm belief are at work in the lives of believers.
