The book of Acts details the beginnings of the early church, their stumbles, their questions, but most importantly, the leading of Jesus by His Spirit which was sent to guide. That same Spirit is the one that leads and guides us as well.
Right after Jesus’ ascension, He told his disciples to wait for the Holy Spirit. Waiting is never easy; when the disciples waited, they did something wonderful, they prayed. In the scriptures it is hard to find waiting without the accompaniment of prayer.
