The Holy Spirit was poured out on Jesus’ disciples on the Feast of Pentecost, celebrated on the 50th day after Passover. According to Jewish tradition, this was also the day God gave the Ten Commandments to his people. Mount Sinai was the shadow. Pentecost is the reality for us. The law is now written on our hearts (Jeremiah 31:33). The Holy Spirit dwells within us. Pentecost is also associated with baptism: “Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.” (Acts 2:38).
