What is God’s will? I think the only what to answer this question would be to look at His spouse, our Holy Mother Mary. Once she accepted to do the will of God “Behold the handmaid of the Lord; be it to me according to your word.” not only was she giving in to God 100% but also giving up her life to sere Him. She no longer had Free Will, but God’s Will. Meaning, no matter what she did, it was pleasing to Him. Mary, is then, God’s will in the physical being. She was also “Full of Grace” meaning she was unable to offend God, because she was sinless.
