Its not just sufficient to just pray we must also act ~Bro Eli
Prayer is a channel the only valid channel of communication between heaven and earth, not everyone will understand the weight of that statement but to those that are in christ Jesus,
Believers mostly are ignorant about these facts they rarely come to understand the place of faith and action, despite reading that portion of the Bible often, that faith without works is dead, the believe is that we serve an all sufficient God and since we're created in his image he will provide all we need obviously without thinking how God will make that happen.
you see the issue of prayer is a very delicate one, because not everyone really understands how it works to produce results.
I was speaking with my friends also had a privilege of sharing with a few group of person in our fellowship about how God answers prayers....
A lot of people especially believers in christ really do not know how God answers prayers so they just pray and believe in their heart That God will answer and then go to bed, not really paying attention to what God is saying, they lack the understanding that prayer is a two way communication system we talk to God and God talk back to us, but no they only talk to God and expect a miracle....
Bro Eli gave an insight, if you're are believing God for anything say a house after that prayer go on look for a job when you get it work had safe up and then you will have enough money to buy or build a house, that way God has answered your prayer, the difference between doing it alone and involving God however is that God will help you along the way when you have taken your first step, God shows up through favour with God and with men, blessing, open doors, promotions etc....
