1 Thessalonians 3:11-13

Here we have Paul's prayer - which is a continuation of the previous paragraph. He indicates that they have been praying night and day that Paul and his crew would be able to return to the Thessalonica to encourage the church and continue their instruction in the faith. Here, he prays the actual prayer. His concern is that the the Thessalonian church is not complete in their faith - that there is something lacking that Paul needs to teach them about in person (see verse 10). Based on what Paul prays about, it could be that they are lacking in love and are not as strong as they should be.
Paul asks for three things in his prayer: that God would allow him to return to them, that God would increase their love for each other so that it overflows out of them and that God would strengthen them so that they would not fall into impurity. This indicates Paul's deep love and concern for the Thessalonian church. He longs for them and for their "success" and wants to do anything to help them.
If I could boil my requests down to three for my students, I'm not sure what I would pray. Probably that they would not be selfish and learn to see and love others with eyes and heart of Christ, that they would be strong in their faith - not just in knowing what they believe and how to defend it but in living it out, in staying faithful to the call of Christ - and that they would discover the incredible joy of knowing and following Jesus. Without putting a lot of thought into it, I think that's what I would ask for.
