but let each prove his own work, and then he will have his boast in what belongs to himself alone, and not in what belongs to another.

For each shall bear his own burden.

For he that sows to his own flesh, shall reap corruption from the flesh; but he that sows to the Spirit, from the Spirit shall reap eternal life:

See how long a letter I have written to you with my own hand.
