Just before being betrayed by Judas and arrested, Jesus sought some solitude in the garden of Gethsemane, where “he fell on the ground and prayed that, if it were possible, the hour might pass from him. And he said, ‘Abba, Father, all things are possible for you. Remove this cup from me. Yet not what I will, but what you will.’” (Mark 14:35-36). Jesus knew He was soon to die.
Donald McKim notes that “In Aramaic, the language Jesus spoke, Abba is the word for ‘Father.’ It is a term that expresses the closest and deepest intimacy of the relationship of parent and child.” Jesus knew this intimacy even on the way to the cross.
McKim also quotes Philip Melanchthon, who said: “’Abba, Father’. By this he taught us that these two things are required in prayer, namely, the ardent affection of the mind and the faithful trust of children toward God: these two words testify that both of these aspects were present in Christ.”
The Father loves us always, even on our most difficult days. Trust Him in prayer today.
