That is the charge to pastors and really it should be the practice of all followers of Christ--to interpret the Word of God accurately, to handle it carefully.
I was challenged (convicted) by two passages of Scripture that are frequently mishandled.
The first was pointed out by Kevin Deyoung here and deals with Matthew 16:18. What exactly are the "gates of Hell" which will not prevail against the church?
The second was from Joshua 24:15 pointed out here by Justin Taylor. What is the choice that Joshua is challenging the children of Israel about? It's not what you might think or have always believed.
