Peter Jeffery is one of my favorite present preachers.  I have recently found several simple talks he has recorded for youtube.

The first is an invitation to those who know the gospel but have not committed themselves to the great gain for fear of the risk of what they may have to give up.

The second is a parable of a train ride that reminds us of what we have in Christ

How simple salvation is! How great it is!

The doctrine of divine election to salvation is profoundly biblical and dear to the heart of well-taught believers. But properly understood it ought to inspire evangelism, not frustrate it. In Romans 9 Paul spells out this doctrine very clearly. Salvation does not depend, says verse 16, on man’s desire or effort, but solely on God’s mercy. In the next chapter, however, the apostle declares equally clearly that no one can be saved without hearing the gospel (Rom. 10:14-15), and that none will hear unless we go and tell them. Even though a man be chosen in Christ before the foundations of the world (Eph. 1:4), he cannot be saved unless he hears the gospel. God ordains not only the end of salvation but also the means.
