Paul continues his crusade to help people to understand the freedom they now have since Jesus fulfilled the law. New converts then and now are not compelled to travel to Jerusalem and make sacrifices each year nor are we expected to meet any requirements of the law. We are required to love the Lord, our God, with all our heart, strength, mind and body. If we do this, we will see changes in our lifestyle. Not because of some written laws but because the love of God constrains us. We respond to the love of God. It is His love for us that keeps us.
2 fixing our eyes on Jesus, the author and perfecter of faith, who for the joy set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.–Hebrews 12:2 (NASB)
6 For I am confident of this very thing, that He who began a good work in you will perfect it until the day of Christ Jesus.—Philippians 1:6 (NASB)
Our focus is not to be on requiring others to take communion as often as we do or if they worship more reverently or loudly than we do (I could go on but you get the picture). We should be focused on making disciples that obey Jesus because they love Him, not in making clones that worship and/or serve like we do.
