"And it came to pass, as Peter passed throughout all [quarters], he came down also to the saints which dwelt at Lydda. And there he found a certain man named Æneas, which had kept his bed eight years, and was sick of the palsy. And Peter said unto him, Æneas, Jesus Christ maketh thee whole: arise, and make thy bed. And he arose immediately. And all that dwelt at Lydda and Saron saw him, and turned to the Lord." (Ac 9:32-35 AV)
Let's marry that to this …
"Then said Jesus unto him, Except ye see signs and wonders, ye will not believe." (John 4:48 AV)
How is it that people can come to believe and turn to the LORD through the witness of signs and wonders? I suppose it is much the same as knowing that the power of God unto salvation is found through the Gospel of Jesus Christ (Rom 1:16). Our Calvinist fellows would have us believe that salvation is through some caricature of predestinated election independent of any response on the part of men and women yet here we see men and women witnessing miracles and believing because of it. How do Calvinists explain themselves to the children of God?
