Q. 74. What is required in the sixth commandment?

A. The sixth commandment requires all lawful endeavors to preserve our own life and the life of others. 

For no one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church,  because we are members of his body.
Ephesians 5:29-30

Give justice to the weak and the fatherless;
maintain the right of the afflicted and the destitute.
Rescue the weak and the needy;
deliver them from the hand of the wicked.”
Psalms 82:3-4

Rescue those who are being taken away to death;
hold back those who are stumbling to the slaughter.
If you say, “Behold, we did not know this,”
does not he who weighs the heart perceive it?
Does not he who keeps watch over your soul know it,
and will he not repay man according to his work?
Proverbs 24:11-12

But Paul cried with a loud voice, “Do not harm yourself, for we are all here.”
Acts 16:28
