Bible Verses About Union With Christ: Necessary to growth in grace

But doing the truth in charity, we may in all things grow up in him who is the head, even Christ:

From whom the whole body, being compacted and fitly joined together, by what every joint supplieth, according to the operation in the measure of every part, maketh increase of the body, unto the edifying of itself in charity.

And not holding the head, from which the whole body, by joints and bands, being supplied with nourishment and compacted, groweth into the increase of God.
