John 14:15-31 GNT
“If you love me, you will obey my commandments. I will ask the Father, and he will give you another Helper, who will stay with you forever.
Do you have that verse in your Bible?
And the pharisees were perfect at law keeping.
And your point is?
Jesus set the bar far higher than simply law keeping and observing times and seasons and dietary restrictions.
So go ahead, and put yourself under the bondage of law keeping if you want, thinking that it is a way to please God.
Those of us in Christ who have died to the Law are free from such bondage and free to walk in the Spirit.
