When we hate we become blind to the things of God,it hinders our pray life
if we forgive there is nothing between our soul and the Savior and we have a clear channel to pray.God is to love if we love Him we will keep his commandents
Jesus said Ye have heard that it hath been said, Thou shalt love thy neighbor, and hate thine enemy .But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you,and persecute you.That ye may be the children of your Father which is in heaven
