Faith in tongues and confrontment of doubt.

I was praying in tongue last night and half way through the Holy Spirit spoke to me. He said, that by praying in tongue, I have taken a step of faith in believing Him and his gift. And by offering my prayers in tongue, I have taken another step of faith in believing that He is real and His gift is real. How amazing tongues can be, not only to offer prayer but also to add unto our faith.

Regarding the doubt I had last night, Jordan and Holy Spirit guided me to the answer. Jordan led me to 1John4 which was about the spirit of error and Romans7:15-20 which was about the sinful nature within us; while Holy Spirit spoke to me as when we commit sins that gratify our desires but we still believe God is there to forgive us, we are like Paul who sins when he does not want to because of the sinful nature within us. We shall then ask for His forgiveness and repent and He shall give us spiritual life again through His forgiveness. However, when we are like those people mentioned in 1John4, we have the spirit of error within us, we refuse to believe in God and thus His salvation and forgiveness. At such, we are dead spiritually.
