For me trust is believing Jesus and actually obeying Him.
Yes...BUT, if anger is murder in your heart, how can you expect to obey Him? You yourself have said it is impossible for you to never be angry or resent in your heart. So by your own admission, it is impossible for you, despite all your best efforts, to obey and keep the command. So the answer is not to then say: well then, it's not true that anger in my heart is murder, because that would make me disobedient and sinful - a murderer.
Jesus came to show us the truth about who we are and what we need to
do. If we find a problem it is us who are the problem and not what He
has said.
I wholeheartedly agree.
Working it through our hearts, spending time with Him, in praise, in worship,
in His word, will make it plain.
I wholeheartedly agree.
As soon as you start denying His words you have missed it, and are listening
to sin and impurity within ones own heart.
I wholeheartedly agree.
