I am doing the same thing that the saints do for me when I ask them to pray with me to Jesus… to join their prayers to mine, en route to Christ. Since they’re closer to Him than I am, it actually makes even more sense for them to pray for me, than for my earthly friends to pray for me.
Of course, you should continue to pray at all times, but especially before you go on a date or spend time with your boyfriend. Pray that you will make good decisions. Ask for the wisdom, courage, and prudence to avoid temptation and the situations where it lingers. Whether that means you’ll leave the place you find yourself in, surround yourself by others, or end the date early.
