God has told us to renew our mind with his word, how many of us are doing that!, that's why we see believers suffer the same thing unbelievers suffer, just because you are alive in Christ( born again) doesn't mean automatically every good things in God's word will just fall at your feet, you have to teach your spirit, tell your spirit /convince your spirit, that's how you prosper.
It's all about the inner man, you can give a man with a poverty mentality money, he will still come to poverty, because he is not educated on the inside(spirit), he's not changed there!.
How do you educate the human spirit with the word of God, u might ask, it's by speaking to yourself out loud the word, make sure you are hearing what you're saying. Make out time, continue doing that each day, and you will know that something has changed in your life, thankyou.
