for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. Matthew 26:28 (ESV)
This is what we remember when we have communion. Jesus blood was poured out to save the “many” that would put their trust in him, so our sin could be forgiven. The meal they were eating was the Passover which is fulfilled in Jesus as the true Passover lamb of the New Covenant.
Peter said to him, “Even if I must die with you, I will not deny you!” And all the disciples said the same. Matthew 26:35 (ESV)
We must avoid false confidence in the flesh
And going a little farther he fell on his face and prayed, saying, “My Father, if it be possible, let this cup pass from me; nevertheless, not as I will, but as you will.” Matthew 26:39 (ESV)
This is where Jesus in a sense won the battle for our souls, by laying down his own will because his deepest desire was to do the will of the Father. We should be the same.
Though a sinner does evil a hundred times and prolongs his life, yet I know that it will be well with those who fear God, because they fear before him. Ecclesiastes 8:12 (ESV)
This is very encouraging
