John Calvin Commentary 1 Peter 4:10

"according as each hath received a gift, ministering it among yourselves, as good stewards of the manifold grace of God;" — 1 Peter 4:10 (ASV)

As everyone has received, he reminds us what we ought to bear in mind when we do good to our neighbors. For nothing is better suited to correct our complaining than to remember that we do not give what is our own, but only distribute what God has entrusted to us. Therefore, when he says, Minister the gift which everyone has received, he implies that what each person possessed had been distributed to them on this condition: that in helping their brothers and sisters, they might be the ministers of God.

And so, the second clause explains the first. For instead of ministry, he mentions stewardship. And for what he had said, as everyone has received the gift, he mentions the manifold graces that God variously distributes to us, so that each might contribute their own portion to the common good. If, then, we excel others in any gift, let us remember that in this regard we are God’s stewards, so that we may kindly share it with our neighbors as their need or benefit may require. Thus, we ought to be inclined and ready to share.

But this consideration is also very important: the Lord has so divided His manifold graces that no one is to be content with only one thing or with their own gifts alone, but everyone needs the help and assistance of their brother and sister. This, I say, is a bond that God has appointed for maintaining friendship among people, for they cannot live without mutual assistance.

Thus it happens that whoever in many things seeks the aid of their brothers and sisters ought to share with them more freely what they have received. This bond of unity has been observed and noted even by pagans. But Peter teaches us here that God had intentionally done this, that He might bind people to one another.
