Do you trust in Jesus's death and resurrection for the forgiveness of your sins?
Do you trust/believe that the bible is the word of God?
Do you obey it? Now that is a very big question. Let me make it simpler.
Do you obey the ten commandments? Not to earn anything, but as a gesture of your love for Jesus.
Think about it, one of the most common breaking of the 10C, is the second, the use of ' Oh my God, [bless and do not curse][bless and do not curse][bless and do not curse], Jesus, etc etc etc.
But trust is far more than this.
At some point in your life, the world will crash around you, job loss, death of a pet, parent etc.
What will you do then? For the Christian they can blindly trust God, seek strength from him to get through those minutes.
That is when one trust God.
