13 This book is divided into two main sections. The first, composed of chs. 1--3, reveals the blessings and the position the church has obtained in Christ in the heavenlies. The second, comprising chs. 4--6, charges us concerning the living and responsibility the church should have in the Spirit on the earth. The basic charge is that we should walk worthily of God's calling, which is the totality of the blessings bestowed on the church, as revealed in 1:3-14. In the church, under the Triune God's abundant blessing, the saints should walk worthily of the Father's selection and predestination, the Son's redemption, and the Spirit's sealing and pledging. Hence, in chs. 4--6 we see, on the one hand, the living that the church should have, and, on the other hand, the responsibility that the church should bear.
