“He that speaketh in an unknown tongue edifieth himself…”
1 Corinthians 14:4
An unwatchful Christian is one who doesn’t maintain a culture of building up himself until trouble arises. Edifying yourself is your most important duty as a Christian.
The Spirit of God already works on your inside to will and to do of His good pleasure. When you invest in self-edification, you are more attuned to the things of the spirit.
One major way to edify yourself is by praying in other tongues quite often.
Jude 1:20 says: “But ye, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost”
Everyone who is born again has the Holy Ghost. And everyone who has the Holy Ghost has the ability to pray in tongues. Don’t cheat yourself. Build up your spirit by praying often in the spirit.
You are also edified when you spend time in quality fellowship with other believers. The Apostle Paul, in 1 Corinthians 14:26, gave instructions to the church at Corinth as to the kind of fellowship that edifies:
“How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying.”
The “Psalms” here do not necessarily refer to the Psalms of David, but to songs that are consistent with New Testament realities. “Doctrine” refers to teaching. Sound teaching will get you edified, as would revelation in line with the word.
Although speaking in tongues edifies you when you pray personally, the culture of interpretation of tongues in corporate prayers should also be encouraged.
Do you realize that everything mentioned in this verse has to do utterance? When you fellowship with other believers, the words spoken are the most important things. You can dance, sing spiritual songs and laugh. But never take teaching for granted.
