In his book In Christ Alone Sinclair Ferguson discusses four points about Christian liberty:

1. Christian liberty must never be flaunted.
2. Christian liberty does not mean that you welcome fellow Christians only when you have sorted out their views on X or Y.
3. Christian liberty ought never to be used in such a way that you become a stumbling block to another Christian.
4. Christian liberty requires grasping the principle that will produce this true biblical balance: “We… ought… not to please ourselves… For even Christ did not please himself” (Rom. 15:1-3)…

He closes the chapter with the following quote from Martin Luther:

A Christian man is the most free lord of all, and subject to none; a Christian man is the most dutiful servant of all, and subject to every one.

May we use our liberty for the glory of God and the good of others and not as an excuse to serve every selfish desire.
