“Then David summoned the priests Zadok and Abiathar, and the Levites Uriel, Asaiah, Joel, Shemaiah, Eliel, and Amminadab, and said to them, “You are the heads of the fathers’ houses of the Levites. Consecrate yourselves, you and your brothers, so that you may bring up the ark of the LORD, the God of Israel, to the place that I have prepared for it. Because you did not carry it the first time, the LORD our God broke out against us, because we did not seek him according to the rule.” So the priests and the Levites consecrated themselves to bring up the ark of the LORD, the God of Israel. And the Levites carried the ark of God on their shoulders with the poles, as Moses had commanded according to the word of the LORD.” (1 Chronicles 15:11-15 ESV)
God is so amazing, so unique. He is a friend, a father, a brother, a helper, a comforter among other things. It is easy to focus on these aspects of His uniqueness and to forget His holiness. We tend to see His approachability as an invitation to do as we want in our relationship with Him. But there are rules to seek God. Repentance is one, faith in Christ another one, and gratitude and reverence others. Grace is grace, but grace is holy. Love is love, but love does not mean disrespect, contempt, or right to complain or test God. There is a place for weakness in our relationship with God, but do not expect God to change His word, His rules for you. He did not even change them for David, the man according to His own heart.
“Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe, for our God is a consuming fire.” (Hebrews 12:28-29 ESV)
