Yes, coming to the front is not the Gospel...
Do you think your Pastor could give an Alter Call, and do it right? All things are Lawful but not all things are Prudent. I think it can be done Prudently. And I have never heard my SCB Pastor tell anyone that coming forward means they're Saved...
My Reformed Baptist Church would always end every Sermon by Congregationally segueing into the Doxology. I would end my Sermons by segueing into Isaiah 55:1-3. Then I'd offer people to come forward...
Come, all you who are thirsty,
come to the waters;
and you who have no money,
come, buy and eat!
Come, buy wine and milk
without money and without cost.
Why spend money on what is not bread,
and your labor on what does not satisfy?
Listen, listen to me, and eat what is good,
and you will delight in the richest of fare.
Give ear and come to [Jesus];
listen, that you may live.
[He] will make an everlasting covenant with you...
If Partial Preterism is True, aren't we in a time of Christ Calling people through Us now?
