1 Peter 4:7 ESV
The end of all things is at hand; therefore be self-controlled and sober-minded for the sake of your prayers.
A mind victimized by emotion and passion, out of control, or knocked out of balance by worldly lusts and pursuits, is a mind that cannot know the fullness of holy communion in prayer with God (cf. 1 Pet. 3:7). A mind fixed on his return is purified (1 John 3:3) and enjoys the fullness of fellowship with the Lord.
