Faith!
We have faith. Right? Do we? Or do we find it really easy to believe and be saved yet really hard to trust and have faith that God is just as sovereign with the mundane as He is with the really important stuff?
It seems that we often fail in realizing the magnitude of the implications of "by grace through faith." This failure appears to be at the hands of cheap grace and easy believeism. It is not popularly preached that though grace is free it was not cheap and therefore should not be marketed as just another consumer commodity. Grace has been so cheapened that the masses fail to see an infinitely holy, righteous, just, and wrathful God. This is a cheap view of God, really it isn't God at all, we only call him God. We accept this idea of God!
Faith in Christ can be flawed and even weak much like Peter's as he stepped out of the boat and into the water only to sink when looking at the wind and storm (Matthew 14:22-33), But it truly was not weak for instantly cried out, "Lord save me." It can be weak and flawed, but it still be genuine faith none the less. Look at this account in the Scriptures, see how bold and confident Peter was in Christ and how he stepped out in faith.
Unlike Peter we don't even make the request! We are huddled at the bottom of the boat in denial as Christians failing to even admit that there is a storm, during which we should be crying out "Jesus to save us." We should in genuine faith cry out to be saved, for the power and strength that we need to over come and suffer well this storm. We must like the psalmist say, "Awesome is God from his sanctuary; the God of Israel- he is the one who gives power and strength to his people. Blessed be God!" That is faith, faith does not say, "why me?" when afflicted it prays, "Lord in my suffering may I suffer well."
Faith is not faith if we only give intellectual assent to gospel facts and have some answers. Faith is genuine when like the disciples in the afore mentioned account you get in the boat when you don't want to and leave into the storm because your master made you. Faith is following your Lord no matter the circumstances. Knowing that it is safer to be obedient and sit in the middle of tumultuous waters that to stand in disobedience while dry and 'safe' on the shore.
Grace is not cheap, our God is not weak, and faith in Christ is regarding him as not only your savior, but your master and Lord. Regard Him as your most Holy Lord (1Pet 3:15).
