Psalm 111:7: The works of his hands are truth and justice; all his commandments are sure.
We cannot hope to live a life like Jesus, but we can be sure to try to aspire to living more like him!
There is nothing wrong with aiming high but make sure you do not get down because you can never reach that bar which you have set.
God may be holy, but he is also gracious and merciful - that is how we can hope to live closer to him otherwise we would be lost forever.
Try to follow his commandments, but remember his great mercy as well and ask for that forgiveness - always.
