InChrist the NewSpirit being is unblameable and unreproveable. We are perfect in the NewCreature.
Understanding why Christ did this is super-critical. He did it because He unabashadly and unreservedly loved us - while we were yet sinners Rom 5:8.
When we begin to grasp His love we begin to experience it Joh 15:7.
Nothing is truly enjoyed or appreciated until it is considered in the mind and heart Joh 1:4.
Consider Jesus Heb 3:1, look to the Author and Finisher of our faith Heb 12:2 understanding that ^our faith^ is our life Col 3:4.
In Him we live and move and have our being Act 17:28.
We are accepted in Him Eph 1:6.
