Every family or persson needs to do DD to get the word of life. It is vital to Christian life (spiritual life). We need to study and undertand the word, grow in faith and know who you/we are in Christ. I enjoyed reading DD messages, apply to my daily life encouragement, motivation and knowing GOD will take me/us through obstacles.
I've personally learnt that DD helped me undertand the spiritual side in depth with more understanding in each lesson. these teachings taught me how to apply it into my everyday life.
