Jesus prayed alone, in public, before meals, before healing, after healing, before important decisions, he prayed to follow The Will, He prayed for us, He also taught us to pray.
Three petitions for God: God’s Name, God's Will, and God's Kingdom in the Lord's Prayer. Then three more for us: Our bread, Forgiveness, and Temptations.
When a prayer seems to go unnoticed or unanswered this should move us further into relationship with Jesus.
We should ultimately be developing a relationship with The Lord through prayer.
Notice that Jesus' prayer in the garden seemed to go unanswered but he was submitting to His Father's will.
