I don't think you've ever took a Scriptures class because you don't seem to understand those verses. Almost all of them are talking about how if you have faith and put your hardest into something then you can accomplish what you believed to be impossible. It's basically Nike's slogan of "Just Do It". The ones actually about prayer like the first are saying that when you pray you are knocking on God's door and he'll open it for you since you seek him and you can speak with him just like you wanted. Prayer is an inner conversation with God in which you reflect and speak to him. You probably think that praying is just thinking in your head "I pray for this, I pray that this happens, I pray for this person" when really you should be speaking to God "Dear God, I know that I haven't prayed very much but I'm hoping to find the strength to commit to praying more often and talking to you. I had a very fun experience with my friends today and it's a blessing to have such loyal people who are there for me and I'm going to do my best to be good back to them...etc." You're supposed to have a conversation with God and reflect and have dialogue. It's not a wish box of any way.
