Rejection

So my eyebrow ring is rejecting again. Which isnt as gross as it sounds, it just means my body doesnt like the forgein object and natural biology is pushing it outwards. And its almost like I dont care, becuase I know its free to get it redone. However, there is still hassle in going to the peircer, getting a needle shoved through my face again, and enduring another 8 weeks of special care and healing. And I began thinking that this is the same attitude I sometimes have with sin. God will tell me to do something, or not to do something and sometimes I dont obey becuase I know I have free grace as a daughter of the king. Which in essence is the truth becuase there are no limits on Christs grace. But to recieve that free grace I first must go through the process of repentance (asking for forgivness and turning from sin) which if Im going to compare this with my eyebrow then its a hassle. The harsh reality of it all is that by not doing something the LORD tells me to do, or doing something He tells me not to do, I am simply rejecting Him. And my relationship with God would be a whole lot deeper if I would stop rejecting Him and just obey. Just like my pericing would be a whole lot deeper if it didnt reject. Please add your thoughts to this or some scripture to convict me further.
