Psalm 98 is a song glorifying the Judge of the World. And the spontaneous response to the Judge of the World is not fear but Joy!
burst into jubilant song with music; Ps.98:4
This joy comes from knowing we have a judge who is head-over-heels in love with us. His judgement is not based on the law but based on grace, undeserved favor. So, today I step out in spontaneous joy knowing yes I am a sinner, yes I will face judgement and yes my Judge loves me.
