My life is in God’s hands.

¹⁴ But I trust in you, Lord;
    I say, “You are my God.”
¹⁵ My times are in your hands;
    deliver me from the hands of my enemies,
    from those who pursue me.

David was expressing his belief that his future was in God’s hands. Life’s circumstances are under God’s control. God loves and cares for you, so knowing that enables you to keep steady in your faith.
