Ephesians 5:1 Therefore be imitators of God, as beloved children. And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God.
Leviticus 11:45 For I am the LORD who brought you up out of the land of Egypt to be your God. You shall therefore be holy, for I am holy.”
Matthew 5:48 You therefore must be perfect, as your heavenly Father is perfect.
Luke 6:35-36 But love your enemies, and do good, and lend, expecting nothing in return, and your reward will be great, and you will be sons of the Most High, for he is kind to the ungrateful and the evil. Be merciful, even as your Father is merciful.
1 John 4:11 Beloved, if God so loved us, we also ought to love one another.
The idea is simple – that we are to make God our example and model. What good does it to us to compare ourselves against others. It is a very practical application of being a Christian, born again, a new creation. Parents know firsthand how much training, encouragement, and repetition is required in raising an infant to a young adult. From early on most will try to model how to walk, talk, and think appropriately. Model yourself after God’s Holiness. We are told to meditate on what God has done, who He is, and what He can do. We are told to fearfully respect, honor, and glorify Him. We are told to praise and worship Him. Here we are given practical application of this – model how you think, how you act, and what you do after God’s demonstrated love, mercy, and grace. God’s behavior toward us becomes our measure for our behavior towards one another.” It is important to see that God is far more than our example. Many errors come into the church when Jesus is presented only as an example of behavior. We are not saved by the example of Jesus, but once saved His example is meaningful to us. God is more than our example, but He is also our example.” (Guzik)
As we do imitate God, we become representatives of God, especially before those who have shut God out of their life. “What are we sent into the world for? Is it not that we may keep men in mind of God, whom they are most anxious to forget? If we are imitators of God, as dear children, they will be compelled to recollect that there is a God, for they will see his character reflected in ours. I have heard of an atheist who said he could get over every argument except the example of his godly mother: he could never answer that.” (Spurgeon)
