"Bearing Testimony The night after receiving so great a blessing, I attended the advent meeting. When the time came for the followers of Christ to speak in His favor, I could not remain silent, but rose and related my experience. Not a thought had entered my mind of what I should say; but the simple story of Jesus’ love to me fell from my lips with perfect freedom, and my heart was so happy to be liberated from its bondage of dark despair, that I lost sight of the people about me, and seemed to be alone with God. I found no difficulty in expressing my peace and happiness, except for the tears of gratitude that choked my utterance. LS 40"
"And let them sacrifice the sacrifices of thanksgiving, and declare his works with rejoicing."
Both passages describe expressing gratitude and sharing one's experience with God's grace publicly. EGW's passage illustrates the principle of declaring God's works with rejoicing.
"For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist."
EGW describes speaking freely and without premeditation, which aligns with the promise in Luke 21:15 that God will provide the words to speak.
"Elder Stockman was present. He had recently seen me in deep despair, and as he now saw my captivity turned, he wept aloud, rejoicing with me, and praising God for this proof of His tender mercy and loving kindness. LS 40.2"
"I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance."
Elder Stockman's rejoicing over EGW's changed state mirrors the joy in heaven over a repentant sinner, as described in Luke 15:7.
