We are responsible for maintaining our fellowship with Him by doing the works that He has appointed for us to do. For instance, there must be continuous exercise of prayer, study into His Word, and seeking to be like Him. We seek Him because we grow to admire—indeed respect—His love and character, appreciate the purpose He has brought into our lives, desire His merciful forgiveness, and realize He is our Benefactor in every aspect of life. However, we must do all of these things in faith.
Notice Paul's counsel in II Corinthians 5:7: "For we walk by faith, not by sight." Like life, walking is a continuous process. Thus, when Hebrews 11:6 says, "He who comes to Him must believe that He is," it means far more than just assenting to a vague idea of a "First Cause." Under the New Covenant, we are dealing with a living Personality working within His creation.
To walk by faith is a practical responsibility. It results from believing in His character and His works as revealed in His Word to the extent that we trust Him and submit to His commands in every area of life. His character is a major reason why we must continue to seek Him: so that our knowledge of Him is continually sharpened and refined to inform our imitation of Him in our lives. Otherwise, we will be pursuing a phantom designed by our own imaginations. We need to grasp as much of His transcendent holiness, supreme sovereignty, almighty power, and perfect justice, as well as His abundant mercy and wonderful grace.
Hebrews 11:6 emphasizes that He is a Rewarder, a Benefactor to those who come to Him and consistently walk with Him by faith. He rewards those who, as a way of life, seek Him in anticipation of His treating them with patient, respectful kindness, even abundance, as He works to create us in the image of Jesus Christ.
Hebrews 11:5-7 balances reward with duty. Together, these verses show that, to be rewarded, we must walk with Him and seek Him. Walking and seeking are where "works" come into play, troubling those who believe in the incomplete Eternal Security doctrine.
In summary, walking with God and seeking Him by faith require keeping God in mind combined with making the efforts of obedience and any sacrifices of time, energy, and rejection by worldly family, friends, and business associates. Nevertheless, these result in being rewarded by God.
