In a day when many contaminants have been introduced to the pure message of the Gospel, let's be sure that what we preach is "pure Gospel", which is 1. the Person of Christ 2. The Work of Christ 3. According to the Scriptures 4. Repentance and Faith (alone) and 5. Forgiveness of sin and eternal life. If our understanding of the gospel is pure, then we will preach it with certainty.
