In the Garden of Gethsemane, Jesus looked full into the cup of God’s wrath and the full ramifications of separation from God. Jesus drank from that cup so that not a drop would be left for your or me, and all that would be left for us is a cup of joy. Jesus went through Gethsemane and ultimately His death on the cross so that we didn't have to. The gospel, at its core, is substitution: Jesus in my Place!
