'Responsible' in the Bible

Let us be judged as servants of Christ, and as those who are responsible for the secret things of God.

Who ever goes to war without looking to someone to be responsible for his payment? who puts in vines and does not take the fruit of them? or who takes care of sheep without drinking of their milk?

If, then, anyone takes the bread or the cup of the Lord in the wrong spirit, he will be responsible for the body and blood of the Lord.
