Psalm 4:4
Be Angry, and do not sin.
Meditate within your heart on your bed, and be still.

i happen to think of this verse while chatting with ian (frm my sch) he was angry abt something, n was using strong words against a person who did him wrong.. so i told him, be angry but do not sin.
anyway, reflecting on myself, many times i have been angry, n tempted to sin.. so hope i can always remember this verse whenever i feel angry n tempted to sin.
