We are to preach Christ and him crucified ... the message of the Gospel, the good news of HIS DEATH, BURIAL AND RESURRECTION, is evident in all of the paraphrased messages/sermons in the historical narrative of Acts ...
Folks need to come through our doors knowing Jesus Christ is the WAY, THE TRUTH AND THE LIFE.
I would be disappointed if a message of HOPE and SALVATION in Christ was not preached.
That saved believers were initially and subsequently baptized and are given the gift of the Holy Ghost (eternal life) is believed by an overwhelming majority of Christians.
I am yet to meet a Christian who doesn't believe
Acts 2:38.
