Jesus has just administered the sacrament to the 12 and is now headed into the Garden of Gethsemane with His best friends -- Peter, James, and John. He says He has to go into the Garden alone, but asks them to wait up for Him nearby.
Jesus knelt by an olive tree and humbly checked with The Father if this is what really needs to happen. Heavenly Father's answer was yes, and the process of transferring all the sins and pain of the world to Christ began.
After an hour of torture, Jesus goes to check on His friends and finds them all asleep. He tells them:
"Watch ye and pray, lest ye enter into temptation. The spirit truly is ready, but the flesh is weak."
I love that He says "the spirit truly is ready" and it is only us that is a changing variable. Every time we are ready also, to clean up our lives and follow the Savior, the Spirit is there waiting.
Have you ever seen the movie Serendipity? I swear it is the most frustrating movie on the planet. Two people who are in love are searching for one another, and literally come within feet of each other several times, but don't seem to meet up face to face until the end.
This is probably how Heavenly Father is frustrated (except much much worse) that the Spirit is always within feet of us, but we continually pass it and continue on with our lives in confusion and sadness.
So now we know for sure WHAT we are looking for and also WHERE it is! The next step is meeting up with the Spirit and changing our lives.
