Mark 14:35 (LEB), “Yet not what I will , but what you will [God’s Command].”
John 14:31. LEB, “[Jesus said], so that the world may know that I love my Father and… just as the Father has commanded me, thus I am doing [i.e. going to the cross].”
John 10:18 (LEB), “No one takes it from me, but I lay it down voluntarily. I have authority to lay it down, and I have authority to take possession of it again. This commandment I received from my Father.”
In Jesus’ context, praying “your will,” means, “I will do what you command Me.” It does not refer to ontology, or that is, God’s sovereign plan or causality —although that is presupposed in the definition. If you are praying or saying, “this is God’s will for me,” if it is to be like Jesus, it means you are referring to a command [ or a promise—which are commands] you are obeying.
“I am sick or lack wisdom, thus, let God’s will be done,” should mean, what does God command me in the Bible that I do with sickness or confusion. God commands us that by our faith, we are to actually get wisdom and actually acquire healing. This is what it means to say, “God’s will,” be done in my life–it means obeying His commands like Jesus Christ did. Just as we are commanded by God to us our faith to be saved from God’s wrath and enjoy endless life and joy. Servants are not greater than their Masters.
