In whatever language, address your God, in the name of your savior (and my savior, and the savior of all humankind), Jesus Christ, and express what is in your heart. Give thanks for the things he has given you, for all we have is a gift from him. Ask for those things that you may need (health, guidance, protection, forgiveness of sin, help with work/school, etc. Blessings upon children/parents/siblings, etc (family), friends, etc).
