The Devil traps us in bad lifestyles so that it is difficult to let go and follow Jesus.
Ephesians 2:1-9 (AMP)
AND YOU [He made alive], when you were dead (slain) by [your] trespasses and sins
2 In which at one time you walked [habitually]. You were following the course and fashion of this world [were under the sway of the tendency of this present age], following the prince of the power of the air. [You were obedient to and under the control of] the [demon] spirit that still constantly works in the sons of disobedience [the careless, the rebellious, and the unbelieving, who go against the purposes of God].
3 Among these we as well as you once lived and conducted ourselves in the passions of our flesh [our behavior governed by our corrupt and sensual nature], obeying the impulses of the flesh and the thoughts of the mind [our cravings dictated by our senses and our dark imaginings]. We were then by nature children of [God’s] wrath and heirs of [His] indignation, like the rest of mankind.
4 But God—so rich is He in His mercy! Because of and in order to satisfy the great and wonderful and intense love with which He loved us,
5 Even when we were dead (slain) by [our own] shortcomings and trespasses, He made us alive together in fellowship and in union with Christ; [He gave us the very life of Christ Himself, the same new life with which He quickened Him, for] it is by grace (His favor and mercy which you did not deserve) that you are saved ( delivered from judgment and made partakers of Christ’s salvation).
6 And He raised us up together with Him and made us sit down together [giving us joint seating with Him] in the heavenly sphere [by virtue of our being] in Christ Jesus (the Messiah, the Anointed One).
7 He did this that He might clearly demonstrate through the ages to come the immeasurable (limitless, surpassing) riches of His free grace (His unmerited favor) in [His] kindness and goodness of heart toward us in Christ Jesus.
8 For it is by free grace (God’s unmerited favor) that you are saved ( delivered from judgment and made partakers of Christ’s salvation) through [your] faith. And this [salvation] is not of yourselves [of your own doing, it came not through your own striving], but it is the gift of God;
9 Not because of works [not the fulfillment of the Law’s demands], lest any man should boast. [It is not the result of what anyone can possibly do, so no one can pride himself in it or take glory to himself.]
