"Into thine hand I commit my spirit: thou hast redeemed me, O LORD God of truth." Psalms 31:5 KJV
This is Christ on the Cross crying out from the Old Testament hundreds of years before the Cross. Crying out to the God of Truth.
He was an innocence man. The only one. The just dying for the unjust. But suffering unjustly because of His innocence. He appeals to the God of truth. He is not asking for justice. He is claiming past redemption in the present moment of hardship.
The weight of Christ's blood tips the scales of justice. It is so heavy nothing can match it. A God of truth must honor it as outweighing anything else. Jesus used this leverage to be raised from the dead. It was His legal loophole.
If you have ever played with a scale you know that if you put a huge weight on one side you can pile small things on the other and the scale will not even move. It is stuck.
The cross freezes the scale of justice in our favor. Once frozen for us it also can not be used to measure anything else either.
"All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any." 1 Corinthians 6:12 KJV
"All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not. Let no man seek his own, but every man another's wealth." 1 Corinthians 10:23-24 KJV
The God of truth who can not condemn Christ also now can not condemn anyone who comes under Christ's covering.
The power we are under is the power of Love under the umbrella of Christ and His life. It is not about right and wrong it is all about redemption. That is the measure we measure with in our minds. That is the measure Christ measured with on the cross.
