James 4:3 -Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts.
How have you been praying? Have you been focused on satisfying your selfish needs only? Let me share with you some ways to pray right or better;
Have a wider mentality, stop saying stuff like "Lord bless me", start saying things like "Lord make me a blessing".
Stop praying with a limited vision; stop praying to just get by, start praying for wisdom to do the right things. For example, stop praying for gifts of money and start praying that money would work for you.
Stop praying for easy lives, start praying with the courageous mentality. Without trials there can be no triumphs, without pain there can be no power, no groaning no glory. Be strong and be of good courage. You are not just an echo in life. Your voice will be heard when you begin to fearlessly solve real problems for humanity. Your works will come to limelight in Jesus name.
