Jesus is our only master - Gospel message of God's word

8 "But you must not be called masters, for one is your Master of you, and you are all brothers.
9 The call anyone on earth 'father', because you have only one Father who is in heaven.
10 Nor should you be called 'leaders', because you have only one head, even Christ. - Matthew 23: 8-10

The word is very clear the Lord Jesus Christ is guiding us that we should not call anyone master, father (For spiritual father) or chief. He said:

We are all brothers and sisters.

And we can not forget ever;

Our unique and good shepherd is the Lord Jesus Christ.

You are all brothers - Matthew 23: 8

Amen and thank God. Stay in the peace of the Lord Jesus Christ.
