1 Corinthians 14:4 (NLT): "A person who speaks in tongues is strengthened personally..."

In 1 Corinthians 14:2, it explains speaking in tongues as a language not understood by anyone but the Spirit of God. It's a spiritual language communicated between His Spirit and ours. As we pray in tongues, we pray the perfect will of God in and over our lives and any situation the Spirit of God leads us to pray over. The devil doesn't understand it, so he can't interfere and neither does our natural mind understand it, so our own reasoning can't interfere with our faith either. Praying in the Spirit, or tongues, activates and stirs up the power of the Holy Spirit inside of us - like powering us up from the inside. It makes the power of God - that resides inside us - rise up, energize and dominate every part of us. It's a wonderful gift that empowers and strengthens the believer as we speak God's perfect will into existence. Paul knew the tremendous value speaking in tongues was, and he encouraged the believers of the early church to operate in this gift frequently. If you're needing an extra dose of inner strength today, yield yourself to the Holy Spirit and let Him pray God's perfect will in and over your life as you pray in tongues.
