1 Corinthians 14:12

So also ye, since ye are zealous of spiritual gifts, seek that ye may abound unto the edifying of the church.

'So also ye' -This demonstrates that the tongue-speakers were no exception to the rule laid down in the preceding verses. They couldn't claim an "exemption" for their spiritual gift.

'since ye are zealous of spiritual gifts' -'eager for gifts of the Spirit.' (NEB); 'ambitious for spiritual endowments' (Gspd) Paul is not against "zeal for spiritual gifts", rather Paul is attempting to direct such zeal towards gifts that edify the congregation. 'Paul's present concern is to capitalize on their zeal, or more accurately, as before, to redirect their zeal.' (Fee p. 666)

'seek that ye may abound' -'since they have such zeal for the manifestation of the Spirit, they should direct that zeal in corporate worship away from being "foreigners" to one another toward the edification of one another in Christ.' (Fee p. 666)

'be eager to excel in such as will build up the faith of the Church.' (TCNT)

'the edifying of the church' -Which infers that the benefit of the body is more important than the praise that might come upon one individual in the body. Spiritual gifts were not designed to elevate individuals, rather they were designed to edify the body.
