"Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you." [Matt 7:7]
God's providence is somewhat of a mystery in that the Scriptures never really explain how it works, simply that it does. God loves us [I John 4:7-8] and wants good things for us [Matt 7:11], but there is an expectation that we seek God out for these blessings. Yes, it is true that the rain falls on the just and the unjust alike [Matt 5:45], but that doesn't mean that we should just go about our daily lives expecting the blessings of God to rain down upon us simply because He wants us to be happy.
I have a good job, a secure income, and somewhat of a cushy lifestyle. I've had the benefit of never really having to worry where my next meal is coming from or how I'll make the house payment next week. But despite all of that, I try to never forget that it is God who has blessed me so richly in life, and I give Him thanks daily for all He has given me. Further more, I continue to ask Him to bless me according to His will, because I have faith in Matt 7:7 that by asking of God, I and my family will be blessed with all that we need.
One final thought on this matter. We must remember that God is not Santa Clause. When Jesus said "Ask, and it will be given to you," He did not mean deliver to God a wish list of everything you want and He'll make it happen. Taken in the context of Matt 6:25-7:12, Jesus is talking about our necessities. God will give us those things we need, not necessarily those things we want. One reason for this is because what we want isn't always what's best for us and could lead us astray. For example, having more money could cause us to covet and stop depending on God, so that may not be what we need.
Pray often, and in your prayers remember to seek God's blessings, for He is simply waiting to be asked so that He may give in abundance.
