Abide in Christ

Abiding in Christ
Grace Walk by Steve McVey, p 145
"As believers abide in Christ, they can act in confidence that the Holy Spirit will guide every thought and deed. Christians need to give as much (my input, more) credit to God's ability to lead us as they give to the ability of Satan to mislead. Grace tasks the responsibility of knowing the will of God off of us and places it on Him.  . . .  Under law, one must find the will of God! In the grace walk, the will of God is revealed by the Holy Spirit to the believer, whose only responsibility is to rest in Him."

My questions are: 
1)  Do I believe these words above? 
2)  What does 'resting in Him' mean and what does it look like in practical terms?
3)  Is my confidence in Him more than my confidence in the evil one or my own fleshly desires?
4)  What am I going to do with His will once it is revealed to me and how important is it to do something?

Grace and Peace
