“All this is from God,” writes Paul, “who through Christ reconciles us to Himself.” (2 Corinthians 5: 18)
Paul does not write, “All this is from you, who — through Christ — reconcile yourself to God” as if Christ’s sacrificial work is secondary to your effort.
If we love God, it is only because He loves us first. In a way, it is as if God loves Himself via His Holy Spirit who dwells within us.
Paul’s message to us is one “of reconciliation, of “God not counting [our] trespasses against [us].” If God decides not to hold our sins against us, why are we so keen to hold them against each other? Why do we forget our sins are nailed forever on the Cross of Calvary?
