My spirit is willing, but my flesh is weak. I think about when the disciples were with Jesus before He was betrayed. Jesus found them sleeping; the spirit is willing, but the flesh is weak.
Matthew 26:39 And He went a little beyond them, and fell on His face and prayed, saying, “My Father, if it is possible, let this cup pass from Me; yet not as I will, but as You will.” 40 And He *came to the disciples and *found them sleeping, and *said to Peter, “So, you men could not keep watch with Me for one hour? 41 Keep watching and praying that you may not enter into temptation; the spirit is willing, but the flesh is weak.”
This encourages me to keep watch and pray without ceasing, that we don’t enter into temptation. The discipline of life change is exhausting, but with the Helper given as Jesus has promised … we can get through it. By faith, the Spirit of God is working in us to stay awake and watch. God is good.
