God knows everything that we need, and He will supply all of our needs. Needs are not what God put us here to fulfill. He put us here to do His work; Seek first the kingdom of God and His righteousness, and all the things that we need to do His work will be provided. Sometimes we think that if we put God first enough, that it will eventually translate to monetary gain. Here's the truth, you can follow God your whole life, and you may be poor your whole life. But if it is a life lived by faith, God will supply your needs.
Today is all that we are promised, and tomorrow might not come and eventually won't come; so we need to think in terms of today. Do what it is God wants today, and He will supply everything you need to do it.
