Sometimes we experience a terrible dryness in our spiritual life. We feel no desire to pray, don't experience God's presence, get bored with worship services, and even think that everything we ever believed about God, Jesus, and the Holy Spirit is little more than a childhood fairy tale.
Then it is important to realize that most of these feelings and thoughts are just feelings and thoughts, and that the Spirit of God dwells beyond our feelings and thoughts. It is a great grace to be able to experience God's presence in our feelings and thoughts, but when we don't, it does not mean that God is absent. It often means that God is calling us to a greater faithfulness. It is precisely in times of spiritual dryness that we must hold on to our spiritual discipline so that we can grow into new intimacy with God.
