When you are tempted to think that you are a better christian than your friends read Luke 18:11

The Pharisee stood by himself and prayed: ‘God, I thank you that I am not like other people–robbers, evildoers, adulterers–or even like this tax collector.

Luke 18:9-14 This parable was to convince some who trusted in themselves that they were righteous, and despised others. God sees with what disposition and design we come to him in holy ordinances. What the Pharisee said, shows that he trusted to himself that he was righteous. We may suppose he was free from gross and scandalous sins. All this was very well and commendable yet he was not accepted; and why not?

He went up to the temple to pray, but was full of himself and his own goodness; the favour and grace of God he did not think worth asking.

Let us beware of presenting proud devotions to the Lord, and of despising others.
