1 Thessalonians 3:5

NKJV: For this reason, when I could no longer endure it, I sent to know your faith, lest by some means the tempter had tempted you, and our labor might be in vain.

GNT: That is why I had to send Timothy. I could not bear it any longer, so I sent him to find out about your faith. Surely it could not be that the Devil had tempted you and all our work had been for nothing!

NLT: That is why, when I could bear it no longer, I sent Timothy to find out whether your faith was still strong. I was afraid that the Tempter had gotten the best of you and that all our work had been useless.
