In Christianity, for a person to grow in godliness, he doesn’t need an instruction manual. What He needs to do is to behold and embrace Christ’s love for himself daily, and that inevitably starts maturing him. It is to grow in his understanding of God’s love for himself that begins to change the heart and causes him to have basic Christian virtues.
In the Bible, to be Holy means always to be set apart. Children of God are regarded as holy because they were set apart for God to live for His glory and also to become more like Jesus Christ. Christian life in that sense, is all about pursing holiness. In this passage, we learn what it means to pursue holiness so that we become like our Heavenly Father and also like our Lord Jesus Christ.
