Hello Brother BrianPaul,
It's a big question, isn't it? It's rather like asking what God's will is for your life, since He created you for a purpose. Your question is a complicated one that has many sides to it.
First and foremost, above everything else, get alone with God, read His Word and pray about it. How is reading the Word going to help you find a job? Because scripture is the main way that God speaks to His people. You won't find a verse that says, "Go worketh for Google," but you will find wisdom. If you seek God's help first, above everything else, you can't go wrong.
I don't know how old you are or the circumstances by which you're living with your mother, but they're not important. What is important is that you honor her. Adult children living with their parent(s) is rarely easy. Regardless, you are commanded to honor her. This is no small matter and how you handle it makes a big difference to God and your future. If we can't obey Him in the things He's already told us, why should He give us anything more?
As for the job, practically, if you need to get a job quickly, pray and make looking for work your job right now. If there isn't an urgency, be sure to spend much time in prayer and trust that He will guide you. Most people fall into whatever job happens to come along and try to make the best of it. God wants more for you than that so abide in Him to know what that is.
I believe that people have the passions, talents and gifts that they have for a reason. We're meant to do something with them. However, that doesn't mean God will put you right in that position to begin with. Life is a process of transforming ourselves into Christ's image. There are lessons to be learned along the way and we have to trust that the Father has our best interests at heart. You keep Him as your focus and let Him take care of you. The plans you make for yourself aren't nearly as wonderful as the one God has for you, so let Him have His way.
You may end up working for a wretch of a heathen for a boss at first, but God will have you there for a reason. There's a purpose for it. The boss may be the person God has decided to teach you something or God may put you there so He can demonstrate Himself to your boss. (Perhaps even both!) Either way, God has a plan and purpose.
So, my advice is to get in the Word, absorb it, meditate on it and fellowship with the Father. More than just for your needs, but just to be with Him. Let Him know, by your actions and your time, that He comes first in your life. He's the priority. That He means more to you than any job. (If He sincerely is to you, that is.) God will lead you and cause the job He has for you to come.
Believe me. I have practical experience with this. He's led me into jobs that I have been hired instantly for, without having a modicum of experience. I work for the Federal Reserve Bank in technical support. I knew I would be hired before I walked into the building and I was. The only thing I knew about computers was how to turn one on! But God gives us what we need, when we need it. I have been able to witness to, and encourage, so many people. I've been through my share of difficulties there, too. It's not a job I particularly want to have, but I know that's where God has placed me, so I don't wish to be anywhere else until He moves me. (And He does!) So, you see? There's no need to worry about anything, but trust always in Him.
