Your gift to us, a Spirit-filled life, is clearly something that we do not deserve nor are we able to earn it. It is a gift of grace, one that gives us access to the mind of Christ, in us, a promise and a reality that exceeds reason.
Satan has powers to tempt us (to sin), granted by the Father. Father, this excerpt makes a powerful point. Satan is claiming that some men love You who are blessed by You and that if their blessings are taken away, apparently for no good reason, they will abandon their faith in You.
