In the Bible, we see people do what they think they should without considering God’s take on the issue. So many do as they see fit, what they “feel” is right.
There is a powerful example in 1 Chronicles of this very thing and it cost a man his life.
1 Chronicles 15:13 The Message (MSG) 11-13 Then David called in Zadok and Abiathar the priests, and Uriel, Asaiah, Joel, Shemaiah, Eliel, and Amminadab the Levites. He said, “You are responsible for the Levitical families; now consecrate yourselves, both you and your relatives, and bring up the Chest of the GOD of Israel to the place I have set aside for it. The first time we did this, you Levites did not carry it properly, and GOD exploded in anger at us because we didn’t make proper preparation and follow instructions.”
We see God in the Scripture seeking to draw us away from the error of simply doing as we see fit. It’s easy to become casual about God and not take Him seriously. All the time there is the pull to simply do as we see fit. Our culture would have the effect of diluting our faith if we become passive about what we believe.
