The Gospel is simple.
Deep, but simple.
When the Lord reveals something, it becomes clear. What was previously hidden becomes not only obvious, but it is in a context.
All the intellectual reasoning in the world can't bring anyone to Christ. Perfect doctrine can't bring anyone to Christ. Trying to be a perfect example guarantees frustration.
The facts are as outlined in the Word of God. All are sinners. All deserve death. Christ died for all. Salvation is free. The gift of salvation must be received. It is personal.
It is the Good News. Jesus Christ is extending His nail-scarred hand to any who will take it.
The Holy Spirit will deliver the message with supernatural penetration. It remains the same through the ages.
