I reviewed this thread and agree with the fact that God does hear all the sincere prayers, whether it comes from a sinner saved by grace, or from a sinner who hasn't yet accepted His grace.
The key ingredients are a sincere prayer coming from the heart.
With your prayer posts and all your other posts, I don't understand why you have not accepted His freely offered gift of salvation offered by His grace?
Of all the prayers you have posted or said in your room or anywhere else, and that He has surely heard, the one He is longing to hear from you is your acceptance of His salvation by grace.
The fact that you pray to Him for others, tells me that you are heading in the right direction, and are still open to the wooing of the Holy Spirit, so keep praying, for the day you stop praying is the day that will do you the most harm.
