"Does the Lord delight in burnt offerings and sacrifices as much as in obeying the Lord? To obey is better than sacrifice, and to heed is better than the fat of rams." 1 Samuel 15:22
As Christ followers, it doesn't matter how many times you've been to Sunday School or how many committees you've served on or how many times you served food at the homeless shelter or how much money you've given the church. What matters most is your obedience to God. Are you going where He wants you to go? Are you doing what He wants you to do when He wants you to do it? Are you saying the things that He wants you to say? Stop trying to please God with your service, and instead, please Him with your obedience.
