Terms starting with A

Accept Jesus into Your Heart

Salvation & Conversion

The invitation to become a Christian by personally trusting and following Jesus — often the closing line of a sermon, a camp talk, or a conversation about faith.

"Decide to trust Jesus and let Him run your life."

Very confusing

Accountability Partner

Youth Group & Camp

A friend you regularly and honestly tell about your struggles, temptations, and goals, who encourages you and asks hard questions — so you're not fighting alone.

"A friend who has permission to ask how you're really doing — and expects a real answer."

Very confusing

Advent

Holidays & Calendar

The four weeks before Christmas, kept as a season of waiting and preparation — for the celebration of Jesus' birth and for His return.

"The countdown to Christmas, with candles and meaning."

Mildly puzzling

Altar Call

Worship & Music

The moment at the end of a service when people are invited to come to the front to commit to faith, pray, or ask for help — usually while a song plays.

"The end-of-service invitation to come up front and make a decision."

Very confusing

Amen

Worship & Music

"Yes" or "I agree" — said at the end of prayers, and in some churches shouted mid-sermon to agree with the preacher.

"Yes. Truly. Agreed."

Mildly puzzling

Anointed

Spiritual Warfare & Supernatural

Specially empowered or set apart by God for a task — and also, literally, having oil placed on one's forehead during prayer.

"God's power is clearly on that person (or: someone just put oil on your head)."

Very confusing

Apologetics

Bible & Theology

Making the case for Christian belief with reasons, evidence, and argument. Nothing to do with apologizing.

"Arguing for Christianity — thoughtfully, not sorry-ly."

Total mystery

Ash Wednesday

Holidays & Calendar

The first day of Lent, marked by a cross of ashes on the forehead as a sign of repentance and mortality — "remember that you are dust."

"The day Christians get a smudge on their forehead and keep it there on purpose."

Mildly puzzling

Assurance

Salvation & Conversion

Confidence that one truly is saved and forgiven — the settled sense that your standing with God is secure.

"Being sure I'm actually right with God — and staying sure."

Very confusing

Atonement

Bible & Theology

How Jesus' death makes things right between God and people. Christians agree it does; they've written libraries on exactly how.

"What the cross accomplished — the repair job between God and us."

Very confusing
