Prayer is a very important part of our relationship with God. It's also a very important part of our faith and trust in God. Throughout the Bible we read accounts about prayer in both the old testament and the new. Jesus even said "my house shall be called a house of prayer". Prayer is simply communicating with God and making our requests known unto Him.
Let me encourage you to pray daily. For yourself, for your family, and for others. Prayer brings heaven to earth and when heaven invades our daily lives and the lives of others, things change.
