The revelation of grace and mercy came as we prepared for the Feast of Passover; it would be the last one before the glory of God was revealed. He suffered and died for this purpose, and I realized that He was showing us how to use the gift of grace and mercy as the yearly celebration neared. We should seek grace from the Lord while we learn about the Courts of Heaven.
We have learned how to appropriate the blood of Jesus in the Courts.
... for the accuser of our brethren, he who keeps bringing before our God charges against them day and night, has been cast out! And they overcame him by the blood of the Lamb, and by the word of their testimony and they loved not their lives unto the death.... (Revelation 12:10-11 ESV)
