I prayed to God to change my heart but nothing has changed my way of thinking or my attitude to show love and not anger. I tried to read the Bible, but I don't feel anything. Please help.
It appears that you are looking for something outside of you to change you, instead of you deciding to treat other people differently. See: Angry Words
So I need to change for myself, instead of asking and waiting fo help; is that how it works? You know, I hear people say to meet God half way and He will do the rest.
"Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling; for it is God who works in you both to will and to do for His good pleasure" (Philippians 2:12-13).
Notice how often God tells us what we need to do and that when we put His teachings into practice, He tells us how those actions change us. "Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy--meditate on these things. The things which you learned and received and heard and saw in me, these do, and the God of peace will be with you" (Philippians 4:8-9).
"Therefore lay aside all filthiness and overflow of wickedness, and receive with meekness the implanted word, which is able to save your souls. But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man observing his natural face in a mirror; for he observes himself, goes away, and immediately forgets what kind of man he was. But he who looks into the perfect law of liberty and continues in it, and is not a forgetful hearer but a doer of the work, this one will be blessed in what he does" (James 1:21-25).
