Grace v circumcision
Acts 15:8 “God, who knows the heart, showed that he accepted them by giving the Holy Spirit to them, just as he did to us”.
Peter has just started opposing the need for circumcision as a sign for salvation. He has taken the council at Jerusalem back to his testimony story of the household of Cornelius. They were all saved and filled with the Spirit before circumcision.
God knew their heart, he didn’t need an outward sign to know whether they were genuine or not, He knew. Circumcision is therefore not for God’s benefit but that of man.
The Holy Spirit is given before they are able to do any performance ritual or any duty to demonstrate to others that they belong to Him. He moves before we move. Such grace!
Man will always demand some attempt from you to prove that you are who you say you are. Resist at all costs. Do not fall into that trap of performance. Stay with grace!
