Thematic Bible: Who purifies their soul

Behold what manner of love the Father hath bestowed upon us, that we should be called children of God l For this cause the world knoweth us not, because it knew him not. Beloved, now are we children of God, and it hath not yet been manifested what we shall be. We know that, when it shall be manifested, we shall be like him; because we shall see him as he is. And every one that hath this hope in Him purifieth himself, even as He is pure.

knowing that not with perishable things, silver or gold, were ye redeemed from your vain manner of life received by tradition from your fathers, but with the precious blood of Christ, as of a lamb without blemish and without spot; who was foreknown indeed before the foundation of the world, but manifested in these last times for you, read more.
who through him have faith in God, who raised him from the dead and gave him glory, so that your faith and hope are in God. Seeing ye have purified your souls in obeying the truth unto unfeigned brotherly love, love one another from the heart, fervently; being born again, not of perishable seed, but of imperishable, through the word of God, which liveth and abideth.
