It's not too late. It's the most important dimension of your life. It should be our bedrock, our foundation.
Spiritual life is dynamic, constant, intimate. What are our needs? We need to be loved. We need to be known. We need to be seen as we are, accepted, appreciated, and loved unconditionally. We also need to love, to express love, to do good, to be a blessing for others, to let love pour forth from the goodness of our hearts. All this can happen in spiritual life. It's what we most desire.
I had a great confession recently. Father told me to set out in the spiritual life with even more ambition and trust than ever. We are not alone in our spiritual endeavors. If you have set out already, keep it up! If you have not, go for it!
