Hebrews 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him (emphasis added, KJV).
Walking by faith require full persuasion. Full persuasion begins with the knowledge of God, and the belief He exists. Though this may sound like “Faith 101,” it is paramount. People obey what they believe and what they want to believe. Those who truly believe that God exists will display some sort of reverence. Those who do not believe do not demonstrate that same reference. To be sure, those who want to live in sin will choose not to believe, even if deep down they at least sense there is a God. Simply put, those who believe that God exists know they will be held accountable. Those who do not want to be held accountable will choose not to believe. When it comes down to it, belief is a choice.
For the true believer, it goes deeper in the sense of commitment. The more committed we are, the more we will want to be fully persuaded. Conversely, the less committed a person, the less the desire is do be persuaded. God is the One who ultimately determines who a true believer is, so this in no way attempts to define who they are. However, this may help bring clarity to it, or at least to what our individual commitments are to the Lord.
Simply put, the more committed we are to God, the more apt we are to believe Him. The more we are persuaded He loves us, the more we are able to trust Him and receive His blessings. The more we trust Him, the more apt we will walk by faith because we believe what He says. When we love God, our desire will be to obey Him, which means we will also want to be fully persuaded of His Word. The true walk of faith cannot be based upon convenience, or whether we like it or not. The Crucifixion was not convenient for Jesus, yet there was joy in the obedience (see Hebrews 12:2).
Full persuasion puts away the questioning: i.e., “Did God really say?” “Did He really meant it.” Understand that God is holy and puts His Word above His name (see Psalm 138:2). Furthermore, He does not lie. His yes is yes, and His no is no. He means what He says, and says what He means. When we ask the Lord to help us with our unbelief, we need to be prepared for exposure. He will not only expose unbelief, He will expose the cause of it. He uproots what He has not planted, which is something to be fully persuaded of.
