"feel a sweet, heavenly peace, an assurance that the Lord will show us our duty; for we desire to do His will.” He accompanied me to the Tabernacle, and opened the services with singing and prayer. It was the last time he was ever to stand by my side in the pulpit. LS 250.3"
Both passages express a desire to do God's will and seek His guidance. The EGW passage describes a feeling of peace and assurance in seeking God's will, which aligns with the sentiment in Psalm 143:10.
