John 20:30-31
Ephesians 2:1-2 says that before salvation, we all are spiritually dead and living according to our sin nature. Those who don’t have a personal relationship with Jesus remain in that state. But when a person places faith in Him, spiritual birth takes place; he or she is made alive in Christ and becomes a new creation who is no longer to live according to the flesh (John 3:3; Eph. 2:5; 4:24).
Our position in the Lord affects everything about us—attitudes, emotions, conversation, and conduct. The ungodliness of our culture no longer fits who we are. As believers, we are to grow in Christlikeness, embracing ideas, thought patterns, and activities that please God, while rejecting all others.
Jesus is the perfect God-man, who willingly took our sins upon Himself and experienced divine wrath in our place. God accepted His death as full payment for our sins, and He raised Jesus from the dead to a position of divine glory (Eph. 1:20). His Spirit now lives within us. So understand who Jesus Christ is, and let that knowledge strengthen your commitment to be like Him.
