Translation
Thus, since you boil with zeal for spiritual _______, you must also zealously desire that they abound for the edification of the called-out-ones.
Paraphrase
Therefore, since you desperately want to have and use spiritual gifts of grace, you absolutely must accompany that desire with a second desire and its corresponding commitment, specifically, that the spiritual gift you are given will overflow with benefits to the body of Christ and that you will only use it for the benefit of others. If you do not do this, you are out of step with God’s purpose for all the spiritual gifts of grace.
A KEY RULE IS REITERATED
Once again Paul states clearly the rule that the spiritual gifts are always given for the benefit and edification of the body of Christ. He stated it clearly in 12:7 and is repeating it clearly here in 14:12. He will say it one more time in 14:26. What’s more, there are many statements in this passage which are built on this rule; without this rule, this chapter makes no sense.
