1 John 4:18-19
18 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. 19 We love because he first loved us.
Trust and obey for theres no other way to be happy in Jesus but to trust and obey. God loves us even tho we are not obedient. We fear because we know we have disobeyed. When we love God perfectly even for an hour we have no fear but when we disobey fear sets in and our love is diminished by the amount of sin we live with. So to love perfectly as God loves us means not to sin and that is not probable. So love God without fear because He loves you perfectly. Trust and obey!
