Father Josh gives us excellent insight into "God's Law", and helps us unpack Jesus' admonishment to "be perfect, even as your Father in heaven is perfect". The bar is set impossibly high by design. You will fail. What God loves to see and what Jesus insists is the path to salvation is that we try. And keep trying.
By trusting in Gods justice, mercy and grace, and letting go of the need to be perfect, and diving into the Christian life, and being gentle with yourself and with others, growth is inevitable.
The rules are your friend, not your nemesis; they are your tools for spiritual growth.
