Dear George (note to self),
You are personally responsible for everything you do, to the God who created this universe. The Bible says every idle word we speak will be called to account at the final judgment, saved and unsaved alike.
Jesus stated very plainly that if you love him and love God, you will keep (attend to carefully, take care of) his commands. “If you love me, you will keep my commandments.” John 14:15 “Whoever has my commandments and keeps them, he it is who loves me. And he who loves me will be loved by my Father, and I will love him and manifest myself to him.” John 14:21 “If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him. Whoever does not love me does not keep my words. And the word that you hear is not mine but the Father’s who sent me.” John 14:23,24
All of his commands are written down in the Bible. It is your personal responsibility to learn what his commands are, and to decide all on your own to obey him. When you choose to disobey God, that is sin, and shows a lack of love for him. Jesus was tortured and died to pay the price for every single time you disobey God.
A lifestyle of sin demonstrates that you don’t love God, and are not a Christian. A Christian is deeply convicted over sin and (as a result) changes lifestyle to stop that sin (maybe not overnight). Life is a long process of becoming sanctified, changing to be more and more like perfect Jesus. “Let this mind be in you, which was also in Christ Jesus:” Philippians 2:5
So, it is not anyone’s job but your own to keep you pure. Other people can help, and the Holy Spirit is with every Christian to remind us of God’s commands in scripture. “But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.” John 14:26
God gives us all the grace (spiritual strength) we need to obey him. “Jesus Christ our Lord, through whom we have received grace and apostleship to bring about the obedience of faith for the sake of his name among all the nations,” Romans 1:5
At the end of it all, though, it is still an individual choice every time to obey God (or not).
