"who also made us sufficient as servants of a new covenant; not of the letter, but of the Spirit. For the letter kills, but the Spirit gives life." 2 Corinthians 3:6 WEB
True story. Our church outreach ministered to an unsaved husband who wanted salvation and deliverance. The wife would not participate in the prayer because she was taught only "Ministers" should "lay hands". Even when the team leaders ensured her they were ministers.
Later, we saw them bringing in groceries which included cases of beer. The very thing from which he wanted deliverance. This is a prime example of "the letter kills". Her teaching did not line up with God's word that says He, "gave to us the ministry of reconciliation" 2 Corinthians 5:18
Although Ministers were present, we were all saved which made us ministers. Her church teachings killed his deliverance thereby killing "their" deliverance.
Make sure what you're being taught is in agreement with God's Word. Do not only feed from your church table. Study the Word. Receive from more than one teaching to see if they line up.
Even the devil knows God's Word and attends church. If the teaching doesn't sound right; if it agrees with government over God's word, "RUN SAVE YOURSELVES".
