Paul writes is Titus chapter 2,
For the grace of God has appeared that offers salvation to all people. It teaches us to say ‘No’ to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age…
People often approach this passage with a particular sin in mind… they have that behaviour they try and hate, they try to stop, but they really love and they keep on doing… and they come to this passage and feel even worse because it seems to imply that the reason they keep doing it is because they don’t understand “the grace of God”. They think to themselves, “Why hasn’t the grace of God taught ME to say ‘no’ to this sin?! Why hasn’t it taught me to be ‘self-controlled’?!? Maybe I’m not even part of God’s grace!?”
That’s Satan talking, twisting God’s word – again.
God grace “is teaching”. Continually and presently. It hasn’t finished teaching. Just think, if it had, you would NEVER sin, in ANY way.
So how IS the grace of God teaching us? Well, what does the grace of God actually do – or allow us to do?
Grace allows us to boldly approach the throne of grace (Heb 4:16). Where sin increased, grace increased all the more (Rom 5:20). See, every time we sin and repent to God, (i.e. asking him for grace again), we are again trusting him at his word that he will graciously forgive again. We are being schooled by His grace every time we pray the Lord’s prayer, “forgive us our sins”. Responding to God’s grace reminds us and teaches us what is unrighteous (our sin) and what is righteousness (God’s grace through Jesus’ life, sacrifice and death for others).
Grace will only be our teacher if we continually go to his lessons.
