Why is the Gospel an Offense?

This service has interactive Chichewa translations!
Why is there opposition to the true Gospel? Why does natural man take offense to preaching that Christ in His person alone completed the work of salvation Himself alone? Why do religious people want to take part in their salvation? How can any be taught of Christ? Why is the greatest opposition to the Truth from so-called christian organizations? Why do some come and listen but return to the vomit of false religion? Why must one believe in, rest in and trust in Christ alone for all things? Why is the fact that God became flesh in His Son an offence to those in darkness? If you don’t know Jesus Christ the Son can you know God?
