The following is a list of changes that took place on the Day of Pentecost. As you will be able to see, the rules changed for those who put there faith in Christ.
God is the source of good and bad
Salvation by faithfulness (Matt. 10:22; 24:13; Rev. 2:10,17,26)
Circumcision necessary to have a part in the Abrahamic covenant
Sabbath laws, special days, feasts (Ex. 23:14-16; Deut. 5:15)
Tithing to the Levites (Luke 18:12)
Christ revealed the goodness of God (John 9:3). In all things God works for the good (Rom. 8:28)
Salvation by grace through faith (Eph. 2:8)
Neither circumcision nor uncircumcision (Gal. 5:6)
Every day sacred if interpreted that way (Rom. 14:5 and 6). Let no one judge you by a religious festival, a New Moon celebration or a Sabbath day (Col. 2:16).
Christ our Passover (1 Cor. 5:7) Christ the firstfruits from the dead (1 Cor. 15:23). We have the firstfruits of the Spirit (Rom. 8:23)
Give as you purpose in your heart (2 Cor. 9:7). Give to the apostles (Acts 4:35). Give to those who instruct you in the Word (Gal. 6:6). Give to the saints (2 Cor. 8:4). Give to “those in need” (Eph. 4:28)
