Peter wept after he heard the rooster crowed at second time, because that moment he remembered that such things has been told by Jesus Christ,and he likewise remembered as he told to Jesus that he is ready whereever Jesus may go and that even his life he will lay down for Jesus Christ,this is I think makes Peter wept.He cried because he realised what comes out into his mouth he can not stand it in action.

Just like we are sometimes we are just like Peter,there are times that we are saying boldly I will give everything to you Lord,even my life.But when the Spirit of GOD speaks unto us and required us to GIVE our tithes, we use to exempt our wallet to justify our Faith to GOD.

Jesus Christ told that whoever Love his mother,father,brother,sister,or family more than he can Love Jesus then he is not worthy of Him ( Jesus ).Love GOD above all things...for He love us more than anyone can.....Remember GOD Loves you,me,and all people out there so much.
