Jesus taught his disciples to love God, and love is first a conversation. Love for others includes praying for them. Thanksgiving is a prayer to express one's gratitude in words. Joy is the expression of praise. And faith is a prayer response to God.
Prayer is therefore the main activity of Christian disciples.
I keep meeting people who are way past my age learning to use e-mail. This is possible because they have become disciples of the Internet. But the computer you need for prayer comes ready installed in your brain. It is so simple that Jesus says you have to become like a little child to learn. And as soon as you focus on a person anywhere in the world you can send them God's blessing, encouragement, renewal, wisdom, healing.
