One of my biggest things is understanding how to read a bible.
Welcome to CF! I've been where you are, at least in some ways you express. reading the Bible and getting light from it is my strength, even before I was born again. so I am very much an anomaly in that regard, but I'll dish my ideas on that one, what works for me. First, I say find a translation or version you're comfortable reading. There have been some flame wars recently on this very issue, which I find utterly absurd! No one version is going to give you 100% understanding of ANY section, and no version is all that bad either. I happen to find something called The Message drives many points home really well, but someone far more knowledgable than I says something called Beck (AAT, for An American translation) and also God's Word (GW) is better. GW is on biblegateway.com, and so is The Message. I haven't found Beck online. Moving on:
1. Approach the Bible with the attitude that it is God speaking to you, telling you about how to relate to Him. Pray with a quiet, meditative spirit, for exactly that. Ask Him to show Himself strong to you, in ways you haven't known yet. It's ok to stir up your hunger, but try not to let that stir up your emotions.
2. Do this every morning, and every evening. We can talk about Scriptural reasons in depth later, but it is God's way.
3. As you read, anything that looks good PRAY FOR IT. Specific examples I've found powerful:
a. Is 50:4 "The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to [him that is] weary: he wakeneth morning by morning, he wakeneth mine ear to hear as the learned. (Jesus got this, prophetically. (Jesus got this, prophetically. Talk about
humility!)
b. That[bless and do not curse]the[bless and do not curse]God[bless and do not curse]of[bless and do not curse]our Lord Jesus Christ,[bless and do not curse]the[bless and do not curse]Father[bless and do not curse]of[bless and do not curse]glory, may give unto you[bless and do not curse]the[bless and do not curse]spirit[bless and do not curse]of[bless and do not curse]wisdom[bless and do not curse]and[bless and do not curse]revelation[bless and do not curse]in[bless and do not curse]the knowledge[bless and do not curse]of[bless and do not curse]him: Eph 1:17
c. Realize EVERY instance of "the wicked man" in Proverbs is you (me / us).
Yeah, ouch.
4. If there's time for more involved praying after this, fine; but more likely there will be other things you need to go do. Don't think they take you away from God because they DON'T! Just don't leave home w/o Him. It's in the doing that prayer seems to be most helpful. "Pray w/o ceasing," keep a prayerful attitude; there is room in His kingdom for
I don't always have the ability to go to church because I work consistently.

Did you mean to say you work
constantly? I've been self-employed for 20 years, and it was really rough at first so I understand. I'll spare you the spiel that's meaningful to me, such as money can be a false god / idol, there really is sense to keeping a sabbath day of rest, etc. None of that is meaningful to you at this point, but this is:
How will I be able to follow the Lord and find faith in him, if I don't have much time to devote?
First of all, reverse that order. Seek Him with your whole heart FIRST, then you'll find Him. Then, He'll take care of the Faith part
THEN you can worry about trying to follow the Lord. I don't need to be a Prophet to tell you that it will be the hardest thing you've ever attempted, and also the most rewarding. Your concern here is very realistic: we DO in fact need to devote some time to Him, just like any other relationship. Of the many many devotionals I've encountered, by FAR the most radical I've ever come across was a link on CF, about how to "pray the hours" of the Eastern Orthodox Church, which I am not a part of, and know very little about.
I can't even imagine following the whole routine unless I lived in a monastery as a monk, but it gives good direction IMHO. And it's always accessible online. It's strikes me as a grand irony that the most radical should be Orthodox, but I use the word to also mean effectual. As in, if you do it to the best of your ability, it will make a difference.
