Hi Figure of Eighty
I was in a similar boat two years ago. I had ten years as a Christian but no fruit. I was even depressed as well.
It wasn't until I seriously read the Bible for myself and stopped depending on the "experts", that I turned around.
People have a lot of opinions on how to draw near to God. Go with God's Word.
We weren't meant to be in bondage to sin.
Jesus told the woman at the well, Go and sin no more. The book of James says we have not resisted to the point of shedding blood (Like Jesus did).
There is no magical faith formula that will make you feel closer to God. Instead, being determined to seek Him through His Word and having the attitude of getting rid of all known sin in your life, were keys to me breaking through and getting the spiritual fruit of Galations 5.
There is no fruit without crucifying the flesh, you can read about that also in Galatians.
There's no silver bullet for getting rid of sin in your life. You must bring your thoughts into subjection. If you can control your thoughts, you can avoid lust, coveting, and worry, to begin with.
The trap I fell into was thinking son was unavoidable and had to be repented of every moment but you could still be expected to be in that' sin tomorrow.
But I believe the Bible supports that repentance is actually a full turnaround from sin altogether. Die to sin and live unto righteousness. I'm here to say, through faith in Christ and seeking the Lord, it's more than possible.
And you have the Holy Spirit, so you can glean understanding from the Word of God yourself. It doesn't require you to have a seminary degree.
Always go with the Bible even if it contradicts what everyone else thinks. You have what it takes to be close to God. He desires to dwell with You in righteousness. Take your sin out of the way. Jesus gives us the victory. We don't have to be slaves to sin anymore. That is where the fruit comes from.
