A Coal, a Voice, and Isaiah’s Calling

Isaiah sees the Lord, is cleansed by fire, and answers a hard summons.

Daily devotional: A Coal, a Voice, and Isaiah’s Calling

Monday, August 17, 2026

Good morning. Today we stand with Isaiah in the temple, where a vision of God, a burning coal, and a spoken “Here am I” turn fear into calling.

Today's Verse

"Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts. Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar: And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged. Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me."
— Isaiah 6:5-8

Reflection

Isaiah does not begin with confidence. He sees the Lord high and lifted up, hears the seraphim, and blurts out his uncleanness. A live coal from the altar touches his lips before any assignment is given. Then comes the question: “Whom shall I send?” Calling often works that way now. A teacher, parent, nurse, manager, or friend first faces truth, receives mercy, and only then speaks a faithful yes in an ordinary room.

Calling begins not with feeling impressive, but with being cleansed and made ready to answer God honestly.

1-Minute Study: Understanding calling

In Isaiah 6, calling is not a private ambition or a dramatic title. It starts with seeing God clearly, seeing oneself truthfully, receiving cleansing, and then responding. Isaiah names his problem specifically: “unclean lips.” The place of his weakness becomes the place God touches. That matters for us. Calling often grows where we know our limits best: the conversation we avoid, the responsibility we feel unready for, the person we need to serve with steadiness. Moses protested that he was not eloquent. Jeremiah said he was only a child. Peter fell at Jesus’ knees aware of his sin. Yet God’s call did not depend on polished self-assurance. It depended on God’s initiative and mercy. In summer ordinary time, when routines loosen and there is room to reflect, it is worth asking: Where has God already placed me? Which duty, relationship, or act of service keeps returning to my attention? Calling is often a faithful answer given in the place where God has already set our feet.

Cross References: Exodus 4:10-12 • Jeremiah 1:6-9 • Luke 5:8-10

Prayer of the Day

Lord of hosts, when Isaiah saw Your glory, he confessed what was unclean. Touch the places in me that need purging, especially my speech and hesitation. When You ask, “Whom shall I send?” teach me to answer with a steady heart, Here am I; send me where I am needed today.

Today's Challenge

Set aside fifteen quiet minutes today and write down one area—home, work, parish, or friendship—where you sense God asking for a clear, practical “yes,” then take the first small step before evening.
