Praying in the Spirit does not refer to the words one is saying. Rather, it refers to how one is praying. In the three places it is used (Corinthians, Ephesians, and Jude), there is absolutely zero reference to 'languages' in connection with this phrase. “Praying in the Spirit” should be understood as praying in the power of the Spirit, by the leading of the Spirit, and according to His will.
Wow now that is the kettle calling the pot black. Who is redefining and re-interpreting scriptures but you.
No where does scripture teach that praying in the Spirit is about attitude or effort or emotion. No where!
Praying in the Spirit is clearly and unequivocally described as NOT praying with understanding - that is NOT praying with our
minds in our own language.
Let us read with honesty Jude 1:
18 How that they told you there should be
mockers in the last time, who should walk after their own ungodly lusts.
19 These be they who separate themselves, sensual,
having not the Spirit.
20
But ye, beloved, building up yourselves on your most holy faith,
praying in the Holy Ghost,
But ye beloved > the saints who do have the indwelling Holy Spirit in contrast to those who do not have the Spirit.
Building up your most holy faith > we exercise faith by putting aside our selfwill and our minds and yield in faith to the work
of the Holy Spirit [God] to pray on our behalf with power.
Praying in the Holy Ghost > a clear reference of prayer that is in contrast to those who are not able to pray in the Holy Spirit
because such people do not have the indwelling Holy Spirit.
And how does scripture teach us all as to who have received the indwelling Holy Spirit?
The Bible evidence of speaking in an unknown tongue; which Jesus himself said would be the sign.
