Every time we repeat the words that Jesus taught us in the Lord's Prayer, we ask God the Father that His will be done on earth as it is in Heaven. Unless you change your thoughts, your words and your actions according to the Divine Will of God, nothing will improve.
Prayer is fruitless when there is no sincerity of heart.
The new heart and the new spirit that you received in the Sacrament of Baptism longs to do the Will of the Lord God in cooperation with the indwelling Holy Spirit. The mind of the new creation is constantly battling against the mind of the physical body. One mind is spiritual while the other is worldly. The evidence of the battle between the spiritual and worldly minds, often being out of control because we do not think before we speak, was mentioned in today's Gospel reading when Jesus told His disciples that He must undergo great suffering and death. This must never happen to you.
