What if you prayed to god, but he doesnt respond to it? And you really prayed very hard and sincerely?
Okay, firstly, you must remember God is not our magic genie. He is GOD! We must come to Him in reverence and awe and not hoping him to do things for you and stuffs like that.
Next, don't think if your prayer is not answered means God is sleeping or He doesn't cares about you. God always hears our prayers. Sometimes He answers with a 'Yes' or 'No' right away, sometimes He needs us to wait.
Then, God is not someone who we only ask from Him. Instead, we should serve Him, bring glory to His name and stuffs like that hundred times more than praying something to happen because he is your Lord.
Next, dun pray cause you need Him to answer you. Pray everyday. when you are close to God, you sure get the answer.
Lastly, God answer when he sees your intention and not only sincerity in you. If you are very sincere in praying that God will help you harm somebody, NO WAY God is going to answer your prayer because the bible says, LOVE YOUR ENEMY!
So, God won't short change you if you devote to him. I'm an example. God did not short change me at all. Taking this week for example, I have been staying real late up night doing my homework and stuffs. I managed to keep myself awake till 3.30AM and be rather quite energetic in school. 2 and a half hour of sleep for me to withstand one whole day is a WOW to me because I sleep a lot last time for those people who knows me they will agree. How did I managed to keep myself awake? By prayer and having my praise and worship songs on. In fact as the time is ticking away, i get more energetic. All thanks to God! Praise the Lord!!
