There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love.
James 4:17
Anyone, then, who knows the good he ought to do and doesn’t do it, sins.
Ephesians 4:16
From him [Christ] the whole body, joined and held together by every supporting ligament, grows and builds itself up in love, as each part does its work.
