If your understanding of Matt 13:4 and 2 Thes 2:9 is catagorically legitimate, why did Christ come performing signs and wonders?
You ask why Jesus came, performing signs and wonders?
1) To glorify God. This is the reason most miracles take place today. When someone is healed, it’s to glorify God, not to benefit the particular person. It advances God’s kingdom, where he wants it advanced (like mission fields)
2) During Jesus time, so that scripture would be fulfilled, and unbelievers would be forced to decide just WHO is the Messiah? In particular, in Galilee, because Jesus was from Galilee, people would not believe someone from Galilee COULD be the Messiah, so Jesus preformed a sign to help them in their unbelief (see John 4:43-54). Note, we don’t have that excuse. (we are not next door neighbors of Jesus)
The enemy HAS USED, and WILL USE (there is scripture for both) signs to deceive.
Let me ask you then, why do you NEED a sign? Does a believer need a sign?
What is faith for then?
