Idolatry has no place in the Body of Christ. We cannot lead anyone to Christ if we do not believe in His exclusive lordship over our lives. We cannot lead anyone to faith in Christ if our faith is compromised by idolatry. We cannot be priests of God and serve another “god”.
There is an innate assumption in the modern church that false prophets are hard to find. However… as easy as it is to know that grapes don’t come from thorns… so it is easy to see the absence of good fruit from the ministry of false prophets among us.
We must fight to maintain God’s truth in our local congregations. We must oppose those who would claim to have knowledge and authority beyond that which is given to us in the Bible.
False teachers/doctrine can be identified. The only remaining question is whether or not we care to identify them and contend for the faith. It is easier to go along with the status quo than to challenge it. And standing up for truth requires that we ourselves know the truth. However, to fail to contend for the faith is to be derelict in our service to Christ.
