'May' in the Bible

that which we have seen and heard declare we unto you also, that ye also may have fellowship with us: yea, and our fellowship is with the Father, and with his Son Jesus Christ:

and these things we write, that our joy may be made full.

My little children, these things write I unto you that ye may not sin. And if any man sin, we have an Advocate with the Father, Jesus Christ the righteous:

And now, my little children, abide in him; that, if he shall be manifested, we may have boldness, and not be ashamed before him at his coming.

Herein is love made perfect with us, that we may have boldness in the day of judgment; because as he is, even so are we in this world.

These things have I written unto you, that ye may know that ye have eternal life, even unto you that believe on the name of the Son of God.
