Prayer is talking with God (not just to him). When you pray, you take time to get to know God and to build a relationship with him. This is important for every Christian. Jesus told his disciples to pray often (Lk. 22:46). Yet prayer is not always easy: how do you start and what can you say?
The most important thing to realise is that God is always with you, even right now while you are surfing the Internet… Nothing prevents you from closing your eyes at this very moment and telling God what is in your heart. Ask him for help, tell him what you find difficult, and thank him for what you have received. That’s praying!
