No, If God Almighty is omniscient, knowing all that is past, present, and future, are not all things destined to occur exactly as God has foreseen them, and If God has foreseen and decreed the course and final destiny of every human, can it truly be said that you are free to choose your life’s course,or your future?
You see, these questions have been debated for centuries, and Prayers is as old as humankind.
The Bible says :All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight.” (2 Timothy 3:16) so any guidance or enlightenment that we receive should ultimately come from God himself. Would it not.
So your prayers cannot do any good unless they are heard, or if you assume a special posture while praying.
No,so what prayers are acceptable to God.
The Bible explains one thing that is necessary for prayers to be acceptable when it states: Without faith it is impossible to please him well, for he that approaches God must believe that he is and that he becomes the rewarder of those earnestly seeking him.” (Hebrews 11:6) Yes, as been explained many times.
Clearly, The Bible requirements must be met if prayers are to be heard.
And with so many who pray show little concern about doing what God requires.
That is why so much earnestness in prayer has not resulted in a better world, you are a poor lot,look at all the thing you lose out on.
