Jesus presented the merit of his ransom sacrifice to his Father Jehovah God upon his ascension to heaven.

Inauguration of the New Covenant. After Jesus died and was resurrected, he entered into heaven to appear before the person of God to present his offering, the benefits of which go first to those taken into the new covenant. (Heb 9:24) Here he acted both as High Priest and Mediator. In harmony with the pattern followed at the inauguration of the Law covenant, Jesus Christ presented the value of his sacrifice before God in heaven (even as Moses sprinkled the blood on the book of the Law [for God was not personally present there]). Then, on Pentecost day, 33 C.E., Jesus poured out the holy spirit from God on the first ones brought into the new covenant, about 120 persons. Later that day about 3,000, Jews and proselytes, were added to the congregation. (Ac 1:15; 2:1-47; Heb 9:19) And just as Moses read the Law to the people, so Jesus Christ clearly enunciates the terms of the new covenant and its laws to those sharing in it.—Ex 24:3-8; Heb 1:1, 2; Joh 13:34; 15:14; 1Jo 5:1-3.
