Why does Satan stop us?

Out of intense longing,

The Apostle Paul made every effort to see the Thessalonian church members (1 Thess. 2:17).

But Satan stopped Paul (v. 18).  What is the purpose?

Perhaps the purpose was to make the Thessalonian church members,

Who had heard the word through Paul and received it with joy (1:6),

Not to be matured, not to believe and be saved (Lk. 8:12-14) but to betray the Lord

When they were suffering persecution (1 Thess. 2:14).
