Many spiritual practices can help us grow closer to God: reading Scripture, prayer, worship, serving others, fasting, journaling, fellowship, or simply spending quiet time with Him.
Looking back, what is one habit that has strengthened your faith the most?
I know it sounds simplitic but, it is true.
Daily reading of the Word. When I stopped intermittently reading here and there, and began actually feeding on the Word, it changed my life.
Peter
You have a pretty complete list already, lol. But to answer the question I would have to say fasting. But it is understood that when one fasts, he naturally prays more while fasting, right? So Fasting and praying sort of go together.
