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 so that your relationship with God can be made right again."”

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
