Obey

1 Samuel 15:22
Does the Lord take pleasure in burnt offerings and sacrifices as much as in obeying the Lord? Look: to obey is better than sacrifice, to pay attention is better than the fat of rams.
 
It seems that knowledge always outweighs obedience. Our ability to actually do what we already know we should do is lacking. For example, I know how to lose weight; eat less and move more. However, I sometimes like to eat more and move less. Receiving godly wisdom and knowledge is the easier part of the process. Actually obeying the knowledge we receive is not so easy.  
Saul learned this lesson in the verse above. Saul knew what to do, but he didn’t do it. He had the knowledge, but lacked obedience. Samuel reminded him that obeying the Lord was the most important thing he could have done.
 
I sometimes find myself asking God to tell me something new, when in reality I’m not doing what I know He’s already told me to do in His Word. In my experience, God usually doesn’t reveal something new if I’m not willing to do what He’s already revealed. Maybe we just need to do what we already know we should be doing. The more people obeyed simple commands in scripture, the more they were trusted with. When in doubt, OBEY. It’s not easy, but it is simple. Obedience takes time, discipline, practice, and ultimately the power of the Holy Spirit working in us. After all, even Jesus learned obedience through suffering.
 
Hebrews 5:8
Although he was the Son, he learned obedience from what he suffered.
