Every Scripture calls us today in some manner to repent and believe afresh, for the Christian just as much as the non-Christian.
If teaching is like a signpost which explains clearly to us where we ought to go and how to go there, preaching is like a friendly but firm shove from behind to get us started on actually going there and to keep us moving.
I coupled these together so that the push mentioned in the bottom quote would have a context. But, what a picture this is and what grace from God to give us preaching for such a reason. I hope you are encouraged as you consider listening to God’s Word this coming Lord’s Day.
