Know body should be trusted except God/your heart is the only trusted friend

I just realized that the best friend any one can trust and believe in on this earth is God and your heart.the people you thing are your best friend are your worst enemy.they will pretend they like you and at your back they will mock and plan evil against you.is only eye we see no body no the mind.even your blood can betray you.only hope in God and believed in your self and you will see change.stay bless
