That text I quoted was from the small catechism.
what is your decision?
try harder?
work more?
believe you are not forgiven?
or have another christian remind you that you are?
2 Timothy 4:2
Preach the word; be prepared in season and out of season; correct, rebuke and encourage--with great patience and careful instruction.
and in case you thought the apostles; prophets; teachers were just like us, and not special:
2 Corinthians 5:20
We [His CHOSEN] are therefore Christ's ambassadors, as though God were making his appeal through us. We implore you on Christ's behalf: Be reconciled to God.
