1 Corinthians 14:2 (AMP)
For one who speaks in an [unknown] tongue speaks not to men but to God, for no one understands or catches his meaning, because in the [Holy] Spirit he utters secret truths and hidden things [not obvious to the understanding].
It is such an honor to be able to talk with God. We not only get to talk to Him but He also talks with us. Prayer is a form of communication. Jesus made if possible through His death, burial and resurrection for believers to communicate with God. God is our Father and He enjoys talking with His children just like we enjoy talking with our children. However God is God and there are times when we may not know quite what to say or how to express ourselves in our natural language to Him. God has made it possible for believers to receive a supernatural prayer language whereby we may communicate things that are beyond our natural understanding. We don't know everything but God does. There are situations , circumstances and much more that we need God's insight and discernment to know what is going on or to know what to do next. The scripture above says we utter or speak secret truths and hidden things, by the Holy Spirit, that are not obvious to the understanding. God is always willing to help us but we must be willing to be helped. It is not logical or natural to pray in a language you don't understand but it is of God and it is supernatural. Just because we may not fully understand this gift God has given to His church to communicate with Him doesn't mean we should not use it. We may not know how our car does everything it does to get us from point A to point B but that doesn't keep us from driving it. God is a good God, every gift from Him is good. God would never give us anything that would destroy or hurt us, He loves us. We must trust Him in everything and never hesitate to do what He ask of us. If God says we should pray in unknown tongues then we obey. If God says love your enemies the we must obey. If God says resist the devil and he will flee from you then we must obey. Whatever He says to do, just do, regardless if you understand it or not, prove your love and trust to Him by obeying what He says without doubting or complaining.
The Holy Spirit helps us to communicate to God in an unknown tongue or language. We who love God count it an honor and privilege to communicate with Him and we take full advantage of every good gift and available help He has provided for us to do so. God knows what we need to live as an over -comer in this life. We must not reject or neglect the precious things He has freely given us. Take advantage of the free gift of unknown tongues and benefit from its power. You won’t regret it!
