To know God's will for my life I need to obey His word and have a personal relationship with Him. When God wants me to do/go/see something, He makes everything work together to that end.
Of course live a spirit filled life and lead others to Him. Right now His will for me is to study His word, be a Godly wife, and mother. Follow His word in my daily working environment, be available to help at my church, and listen to Him through the Holy Spirit! All I can do is be available.
