"Come to me, all who labor and are heavy laden, and I will give you rest." Matthew 11:28 (ESV)
Christianity is not a list of do's and don'ts. In fact, we are invited to lay our burdens, including the burden of trying to be a "good Christian", at the feet of Jesus. When we offer up all of our worries, our lists, our priorities, our stressors, our failures, our burdens, ourselves, our life becomes about only one thing: God and our dependence on Him. He does all the rest.
Those who labour to establish their own righteousness also labour in vain. The convinced sinner is heavy-laden with guilt and terror; and the tempted and afflicted believer has labours and burdens. Christ invites all to come to him for rest to their souls. - from Matthew Henry's Concise Commentary
