It is Jesus's will, God's will, for us to keep the New Covenant Passover. Jesus says only the person who does the will of God can enter the kingdom of heaven. So, only those who celebrate the Passover can enter heaven. Then, how can the door to heaven be opened through the Passover? Let's see what blessing is contained in the Passover. Jn 6:53~56 Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is real food and my blood is real drink. Whoever eats my flesh and drinks my blood remains in me, and I in him.Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. This is the bread that came down from heaven. Your forefathers ate manna and died, but he who feeds on this bread will live forever."
"We trusted in him; let us rejoice and be glad in his salvation"
