"But if you are led by the Spirit, you are not under the Law." -Galatians 5:18
It is possible to be perfect, and to meet every letter of the law, God's original intent. Jesus did it, no problem! But we will always struggle. Thank God's goodness, despite our failings, we don't have to meet the law, because Christ already did! And, His Spirit lives in us. Therefore, if we depend on Jesus, we don't have to execute each and every little detail and rule, rather we can be led by our gracious interceder.
