I had this thought a couple days ago about the argument that abortion proponents make:
The first great sin of abortion is murder. The second great sin of abortion is selfishness: “This is my body, and I have the right to choose what to do with it.”
On the contrary, we hold that “[y]ou are not your own, for you were bought with a price. So glorify God in your body” (1 Corinthians 6:19-20). And that love “does not insist on its own way” (1 Corinthians 13:5). And, “Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others” (Philippians 2:3-4). We as Christians hold that our body is not ours, that we are to give up our bodies and our lives in acts of love to others. This argument for abortion runs completely counter to Christian love. Do we always make decisions based on what we want to do? No–we act based on the example of our Lord, who loved us and gave himself up for us (Galatians 2:20).
