I disagree that I need to show Scripture "warning us about instrumental music when it is bad."
Where does the Bible teach that God has said that all possible combinations of musical elements that can be made to make instrumental music are all good and all pleasing to Him?
Because He cannot judge us except by His words. Luke 12:40-49 says those servants or saints left behind will be judged by stripes per the measure of knowledge that they did have for not being ready & lesser stripes for the lack of knowledge they did not have in being ready; hence there is knowledge from the Word of God to be had. Therefore if there is no warning nor condemnation to any certain kind of instrumental music for which we have knowledge from His words by, how can He judge us with any stripes at al?
Much more importantly, where does the Bible teach that He will accept the offering to Him in worship whatever combinations of instrumental musical elements humans decide to make and think are good?
The question is where does the Bible teach that He will NOT accept the offering to Him in worship?
Answer; God the Father will not accept the offering to Him in worship if they approach God the Father by any other way than the Son in worship; John 14:6 & John 10:1 That means approaching God the Father in giving an offering of worship to Him by approaching the father by the Holy Spirit or the Trinity will NOT be accepted & considered a work of iniquity..
Answer yet again; God the Father will NOT accept the offering to Him in worship if they honor anyone else besides the Son in worship. John 5:22-23 That means honoring the Holy Spirit or the "Trinity" in worship other than the Son in order to honor the Father will NOT be accepted & considered a work of iniquity.
Confirmation to rightly dividing the word of truth can be found in Matthew 7:13-27 in how they broaden the way in the worship place whereby focus on the Holy Spirit in these apostate movements of the "spirit" has brought out claims of miracles, but yet they fall down due to lack of self control when receiving these spirts of the antichrist, assuming they were the Holy Spirit because He was addressed in worship.& to come to them in worship & they came
Jesus cites the solution to avoid that iniquity in Luke 13:24-30
Why the focus on the Son & never on the Holy Spirit? because God is calling sinners away from their practice of seeking spirits & communing with spirits to a personal reconciled relationship with Him ( the Father ) thru Jesus Christ. For believers to abstain from all appearances of evil in proving all things, then the supernatural phenomenon that can be found in the world cannot be found in coming to the Father in worship; hence if found, then they are NOT coming to God the Father in worship by the only way of the Son in honoring only the Son.
Only God can enable you to see the truth in His words of just how bad it is in these latter days for why believers are following the crowd in their man made unscriptural church traditions rather than His words for why only a few will find the way to Him.
