From 1 Peter 1 and verse 22 we learn that the very basis for Peter’s command “love one another fervently with a pure heart” is the prerequisite or “precondition” of a purified soul. Notice what Peter said first, “Since you have purified your souls in obeying the truth [b]through the Spirit in [c]sincere love of the brethren” . Since / Because you have purified your souls in obeying the truth you are now set apart…
"God is Spirit, and those who worship Him must worship in spirit and truth." (John 4:24)
