I can so relate to this, and is written about in Hebrews
Me too! I have many years of "crying a river" based on what I thought God was doing in my life only to find years down the road God had nothing to do with it. Today., most of my prayers are ones of thankfulness to God and what He has done through Jesus for me. Making it my goal to learn more and more about Jesus and who I am now in Him. That is totally different than the way I used to pray and live the Christian life.
I was soooo sincere those years ago but soooooooooo sincerely WRONG. And the Holy Spirit was disregarded by me because I thought He was telling me what my emotions were telling me. I couldn't figure out why nothing was working in life when I was doing what the Bible said and what I had learned. It's about the hidden man of the heart... it's about an inward change that effects the outward. We can't change our outside hoping the inside will be effected.
What most Christians don't realize is we cannot prop up our old flesh and just be a better version of ourselves. No., we are totally NEW CREATIONS IN CHRIST. Learning about our spirit man and how to relate to the Holy Spirit through the spirit. We can't relate to the Spirit by our flesh (our old manner of life) What we are called to do is SEE JESUS and then we will see who we are IN Him.
It always goes back to Jesus where the answers are found, where the love and truth is found. The Bible reveals Jesus and the Holy Spirit points to Jesus.
