You are probably reading this because you hope to have or already have a purpose filled passionate life that matters. Either way, what I've learned over many years of speaking and preaching is that the positive impact of one's life is almost always in direct proportion to the vitality of their relationship with God.
So, in my opinion, there is no greater thing we can do than to develop our relationship with God.
Prayer is a vital component of our relationship with God.
If you'd like to learn to pray better then download 'A Simple Way to Pray' by Martin Luther here. It's powerful, simple, brief and very practical.
All the Best,
