1 Corinthians 14:2 – For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
In that scripture, where it says, no man understandeth him, it is saying that when you pray in the Spirit, no one can understand what you are saying but God; not even satan. This means that the enemy cannot interrupt your flow and he can’t block your receiving.
If you ever want to get the enemy out of your plans, pray in the Spirit. He won’t be able to figure out what’s going on and try to stop you. Many times, when you pray in English, satan can hear you and he may try to sabotage you. He might even try to give you the wrong answer. But, when you pray in the Spirit, he is helpless. The enemy has no clue what is going on – you and God can have uninterrupted conversation!
