Paul commanded that we pray without ceasing in 1 Thessalonians 5:17. Paul is teaching us here that we should never stop praying to God. Philippians 4:6 reads "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God." Colossians 4:2 reads "Devote yourselves to prayer, being watchful and thankful."
