If you are struggling in your finances and in your faith, let me encourage you to take God at his word. Below I have put important promises from God. Read, obey, and do exactly what these verses say. Hold God to his word. Expect that he'll do as he promised. Read the Bible, be obedient, and give as he demands. Then, he promises that you will be successful and prosperous. That's his promise. It is clearly documented (see the verses below). If you do these things and he does not bless you as he has promised, then it is safe to say that theses verses are a lie.
So, read God's word (the Bible) and when you see a promise, you cling to it and trust in him solely to fulfill his promise. If you see something going differently than he promised, pray immediately and tell him that he promised and tell him that you are clinging to that. Remind him that you've done what he has demanded, expecting that he would hold up his part of the promise. Tell him that you are trusting in him and his promises. Have faith that he'll fulfill his promises.
If he doesn't, then it's safe to assume that I am completely wrong and these verses are either (1) a lie, or (2) only meant for the specific people that it was spoken to thousands of years ago and not applicable to Christians today. But, if that be the case, then what else in the Bible can we not trust in? So, you see...there are promises in the Bible, and God has a reputation to upload of being trustworthy. So, all of my faith is in God the Father, God the Son (Jesus Christ), and God the Holy Spirit, and I expect them to fulfill their promises as I do my part as written in their word.
Do God's will and expect him to do as he promised. Talk to him everyday, and if something starts going contrary to what he promised, tell him about it. This is a relationship. It's a two way street.
Here are the verses I'm clinging to for my career as a stock trader.
You do not have because you do not ask God (James 4:2).
