In 2 Thessalonians 3.1-5, Paul requests of the believers in Thessaloniki that they pray for him so that the word of the Lord "will go forward quickly and be glorified." Almost immediately, Paul acknowledges that "the Lord will be faithful."
"Here is the paradox of Christian living: because the Lord is faithful and will guard us, therefore we pray that he will do so. This always sounds illogical to those who aren't engaged in [preaching and praying, the work that apostles and churches share]. Those who are [so engaged] will know that prayer has a power and sense below and above logic. Our praying hearts, minds and lives are put at the disposal of the living Lord, who remains sovereign, but who longs for our collaboration in his work of strengthening the church and guarding it from evil."
-from Wright, N.T., Paul for Everyone - Galatians and Thessalonians (Westminster John Knox Press 2002, 2004), p. 154.
Is it part of the essential character of God that God be logical? Where does it say that? God is love.
