How is God's will done? God's will is done when he breaks and hinders every evil plan and purpose of the devil, the world, and our sinful nature, which do not want us to hallow God's name or let His kingdom come; and when He strengthens and keeps us firm in His Word and faith until we die. This is His good and gracious will. (Small Catechism: The Lord's Prayer, Third Petition)
In the Name + of Jesus. Amen. Do you know God's will for your life? What does God want? What job should you work? What college should you go to? Whom should you ask to prom? Which classes are best for your future? Does God want you to spend your money on this or that? Many people when they talk about "God's will" assume that God is there to micro-manage their lives and they can't make a decision without wondering whether God approves or not.
You are in Christ! You are His child! All your sins are forgiven. Everything you do is sanctified and made holy by the blood of Jesus. You can't not do God's will! But the devil, the world, and your sinful nature will try to get you to go your own way. They don't want you to live like someone who bears the name of Christ. They don't want you to believe God's Word or live a holy life.
That's why we pray the Third Petition. We are asking that God's will be done. His will is that we are kept safe in Jesus. His will is that Jesus be your Savior. Jesus did His will! He never questioned what the Father wanted Him to do. He suffered as He was told and was obedient unto the cross and death to save sinners, to save you who are the target of the devil, the world, and your own sinful nature.
Because Christ kept the Father's will, and because you are baptized into Him, you keep God's will. And whenever you doubt that, cry out that God's will be done to know that He will protect you from such enemies.
And then, knowing that you are in Christ, go and take that job or date that girl or guy or pick those classes knowing that you are child of God and He loves you. In the Name + of Jesus. Amen.
Your gracious will on earth be done As it is done before Your throne, That patiently we may obey Throughout our lives all that You say. Curb flesh and blood and ev'ry ill That sets itself against Your will. (Our Father, Who from Heaven Above, LSB 766:4)
