Salvation is by grace through faith alone, but grace is not to sin or for sin, but from sin.  God by His grace saves us from sin.  Paul talked about this in Romans 6:1-2, “What shall we say then? Shall we continue in sin, that grace may abound?  God forbid. How shall we, that are dead to sin, live any longer therein?”  Did you know that “God forbid” translates the strongest negative in the Greek language?  The Greek term for “God” doesn’t appear, but since there was no English equivalent, the translators gave it the most negative expression they could, so “God forbid.”  Grace is not license to sin.  As much as church members might answer “no” to that as a question, I believe they might live like “yes.”  “If salvation is by grace through faith, do you have license to sin, since it’s all forgiven anyway?”  Are you living like you are taking advantage of God’s grace?  Since we’re not saved by works, then you don’t have to do works, or at least little to no works.  Is that true?  Of course not.  A corollary to that thought relates to the clarity of scripture.  If scripture is not 100% knowable, then men explain how that they don’t need to keep it all.  They would keep it all if they could understand it all, is the excuse.  Yet, God says we can understand it all.  A child can(1 Timothy 3:15).  God’s grace is a powerful agent to change into obedience to God.  Is that what you see happening?
