'Children' in the Bible

Know ye therefore that they which are of faith, the same are the children of Abraham.

For ye are all the children of God by faith in Christ Jesus.

Even so we, when we were children, were in bondage under the elements of the world:

My little children, of whom I travail in birth again until Christ be formed in you,

For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.

For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.

Now we, brethren, as Isaac was, are the children of promise.

So then, brethren, we are not children of the bondwoman, but of the free.
