Thematic Bible: Who purifies their soul

Look at how much love the Father has shown to us [Christians], that we should be called His children! But, that is what we [really] are! The reason the people of the world do not know who we are is because they do not know who God [really] is. Dearly loved ones, we are God's children now, but it has not yet been revealed [to us] what we will be [in the future life, Luke 20:34-36]. But, we do know this, however, that when Jesus is revealed [i.e., at His second coming], we will be like Him [I Cor. 15:49], for we will see what He really looks like! And every person who has set his hope on this [i.e., of being like Jesus], will live [as] purely [as possible], just as He [i.e., Jesus Himself] is pure.

You [should] know that you were bought back [from Satan], from your useless way of life, inherited from your forefathers, not with such perishable things as silver and gold, but with [the] precious blood of Christ, who represents an unblemished lamb, without defect. For Christ was previously known [by God, even] before the world was created, yet was not fully revealed for your benefit until [these] final times. read more.
[It is] through Christ, whom God raised from the dead and honored, that you people have become believers in God, so that your faith and hope could rest in God. [Since] you have purified your souls by [your] obedience to the truth [i.e., the Gospel message], which produces a genuine love for your brothers, [now] you should have this kind of fervent, heartfelt love for one another. You have experienced new birth, not from seed that can decay, but from seed that cannot decay, through the living and enduring word of God.
