"For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. For the good that I would I do not: but the evil which I would not, that I do. Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me. I find then a law, that, when I would do good, evil is present with me. For I delight in the law of God after the inward man:" - Romans 7:18-22 (Read Romans 7:7-25)
Nothing can start without God. Never attempt starting your day, week, month, a business, a journey or a new relationship without God. Involve Him before the take off and if you did, when you call upon Him in the way He answers you.
The idea of sin cannot be conceived without a LAW and a LAWGIVER. If there is anyone who has the power to decide what should be and what should not be, what should be done and what should not be done, it is God, the Creator of all things.
