If you believe why do you refuse to obey?

Are you a servant of Christ but you're always making excuses why you don't have to obey ALL of YHWH's commands and instructions as written in scripture? I'm coming to you in love and pleading with you to let you know why we should all be obedient to our loving heavenly Father who knows what is best for us and wants the best for us. Jesus/Yeshua told us that his brothers and sisters are those who do the will of his Father in heaven. You have your own free will and mind to make up but I want to be a brother to my Master and I pray that I can convince you why you should do the same. Shalom!
