In the introduction of the book of Acts of the Apostle, Luke said "...of all that Jesus began both to do and teach,'.
The word "do" came first , then teach. The teachings of our Lord Jesus came from His everyday life, His daily living was a revelation of God's will and purpose.
God is helping me by His mercies to be a living epistle of His divine will and purpose for my life on the earth.
"To me to live is Christ and to die is gain". Philippians 1:21
