IF quotes are from Amy Carmichael, who was a Protestant Christian missionary that served in India for 55 years without furlough and wrote many books about the missionary work there.
Consider the following in knowing what God's Will is for His children:
BE SAVED - "Jesus answered and said to them, 'This is the work [will] of God, that you believe in Him whom He sent.'"
John 6:29 NKJV
BE THANKFUL - "In everything give thanks; for this is the will of God in Christ Jesus for you."
1 Thessalonians 5:18 NKJV
BE HOLY - "For this is the will of God, your sanctification [holiness], that you should abstain from sexual immorality."
1 Thessalonians 4:3 NKJV
BE GOOD - "For this is the will of God, that by doing good you may put to silence the ignorance of foolish men."
1 Peter 2:15 NKJV
BE WILLING TO SUFFER - "Therefore let those who suffer according to the will of God commit their souls to Him in doing good, as to a faithful Creator."
1 Peter 4:19 NKJV
These passages clearly show what God wants every believer to do. There are many other passages showing God's will without actually using the words, "will of God."
PRACTICAL APPLICATION: If you stress to know, "What does God want me to do?" then at least do the things He has clearly stated. "If you want more light, follow the light you already have."
