So many of us have heard the reason we aren't supposed to use instruments in worship (even saying it is sinful) is because Ephesians 5:19 only says to sing.

Is that what Paul had in mind when he wrote Ephesians 5:19? The only way to know is to check the context. Paul was exceptionally good at making well thought out arguments. His letters aren't bullet list of individual/isolated theological points. He is taking his audience somewhere.

Next is authorial intent - that the authors of the Bible had an original intent when they wrote what they wrote and we cannot understand it for us today until we understand it for them in their day.

Once we understand those two things we go back to what Paul wrote to understand the point he was actually making and it had nothing to do with condemning the instrument in worship.

I believe it is wrong to twist the Bible to make it say things it doesn't actually say and even more wrong to divide over these issues. This calls for repentance.
