That is pretty dangerous stuff. Some truth mixed with deception can be very deceptive indeed.
Paul Washer is a 5 Point Calvinist whose message basically consists of...
1. Recongise and admit how depraved your are.
2. Trust in Jesus
3. Examine yourself to see if there is any change in your life (basically you should be sinning less over time).
Paul Washer denies heart purity in his doctrine and believes reconciliation to God is via a legal transaction which took place at the cross where God views Jesus in the place of a depraved Christian. John Piper teaches the same thing as does Conway. It is a very subtle preaching of "you can sin and not surely die so long as you are one of the elect, imputed with Jesus obedient track record, evidenced by sinning less and less over time." The sin never stops and no true salvation experience can occur under this doctrine.
Ravenhill theology on the other hand is more on the Arminian side instead of Calvinism. The problem though with his theology is that conversion and regeneration is still principled off an emotional experience of "accepting Jesus" and "sinning less over time." The sinning less over time is basically the process that leads to "Entire Sanctifcation" under Arminian theology. Just like in Calvinism the sin NEVER actually stops.
Both Calvinism and Arminianism teach a sin/repent/sin/repent/sin/repent life for a Christian.
The real Gospel involves being set free from the literal power of sin whereby one is held in continual bondage to its service. Repentance is where the bondage is broken through the change of the mind where one's rebellion to GOd is forsaken once and for all and the Spirit of God, the Spirit of the life of Jesus Christ, is received internally. It is through the voluntary submission of this Spirit that one is able to walk in all righteousness and grow in the grace and knowledge of Jesus Christ. One may do wrong ignorantly and be corrected but willful wrongdoing has ceased.
The false teachers above all make an allowance for willful wrongdoing to continue whether it be often or occasionally. It doesn't really matter whether one rebels against God weekly, daily or monthly, the rebellion in itself reflects a state of the mind and heart towards God. One cannot serve sin and serve God, it is one or the other.
The above teachers in the video are extremely dangerous because they present a message which is narrower than many teachers today. Thus people who see problems with a watered down Gospel message very easily buy into these other celebrity preachers whose message does not seem as watered down.
Satan is a master theologian so be very aware of his devices. He is a master deceiver and he deceives the entire world. We are to not be of this world and therefore not be deceived.
Repent and believe the Gospel and therefore be a doer of the word from the heart. Love God and love your neighbour. It is very simple.
