One God and one mediator
For there is one God and one Mediator between God and men, the Man Christ Jesus, who gave Himself a ransom for all, to be testified in due time, - 1 Timothy 2.5-6
The gulf between God’s holiness and man’s sinfulness is massive. Our sin separates us totally and absolutely from our God.
Man has always sensed that gap and has wanted to do something about it. Man has tried all kinds of philosophies and ideas and religions.
But those who do turn to Him find that we do have an advocate – we do have a mediator. Our mediation is not found in religion or practice or ritual or routine or even dead saints or a holy man. We are equal in God's sight to we all have the same mediator.
Apart from Christ no one and no thing can mediate the difference. Mediators try to reconcile the differences between two sides, but the sin gap is so great that it no one can fill it except the God who is offended by our sin.
Praise God that our Mediator is there and willing to mediate when we place our faith in Him.
