There are two kinds of Christians.
“Sink Christians” view salvation like they would a sink. The water of salvation flows into the sink so that Christians can soak up all the benefits: eternal life, assurance in the present, strength in times of trial. Those who adopt this mindset concentrate solely on what the Bible says God has done and will do for them.
“Faucet Christians” view salvation differently. They look at the world as the sink and themselves as the faucet. The blessings of salvation flow to them in order to flow through them out to the wider world. They rightly see that the Bible describes salvation as something that God not only does for them, but also through them.
