Jesus said in Matthew 22:35-40:
One of them, an expert in religious law, tried to trap him with this question: “Teacher, which is the most important commandment in the law of Moses?” Jesus replied, “‘You must love the Lord your God with all your heart, all your soul, and all your mind.’ This is the first and greatest commandment. A second is equally important: ‘Love your neighbor as yourself.’ The entire law and all the demands of the prophets are based on these two commandments.”
He didn't give them a list of things not to do but rather he told them to love.
We need to change our focus. It is not about not messing up, it is about loving God and others. If we are spending our time learning to love God more and not worrying if we are going to do something wrong, our relationship with God will grow. We will be spending more time with God and He will help us work through the sin issues along the way.
It's not about being "good", it's about loving God and letting Him lead us through.
