Heads AND Tails

I thought this was a really unique way of putting salvation, and liked it:

“…in Acts11:18 the apostles respond to Peter’s testimony about Gentile conversions like this: ‘Then to the Gentiles also God has granted repentance that leads to life.’ And in Acts 14:27, Paul and Barnabas report the conversion of the Gentiles by saying that ‘God…had opened a door of faith to the Gentiles.’

Conversion, then, is repentance (turning from sin and unbelief) and faith (trusting in Christ alone for salvation). They are really two sides of the same coin. One side is tails - turn tail on the fruits of unbelief.

The other side is heads – head straight for Jesus and trust His promises. You can’t have the one without the other any more than you can face two ways at once or serve two masters.

This means that saving faith in Christ always involves a profound change of heart. It is not merely agreement with the truth of a doctrine. Satan agrees with true doctrine (James 2:19). Saving faith is far deeper and more pervasive than that.”
