One of the two who heard John speak and followed Jesus was Andrew, Simon Peter’s brother. He first found his own brother Simon and said to him, “We have found the Messiah” (which means Christ). John 1:40-41 (ESV)
Who can tell what might have happened if Andrew had been of a silent, reserved, and uncommunicative spirit, like many a Christian in the present day? Who can tell but his brother might have lived and died a fisherman on the Galilean lake? But happily for Simon, Andrew was not a man of this sort. He was one whose heart was so full that he must speak… All who have received mercy ought to find a tongue, and to declare what God has done for their soul.

The Lord is my Shepherd; I shall not want. Psalm 23:1 (KJV)
The gospel rightly leads us into a personal relationship with Jesus, for his glory, our salvation, and the good of others. If our Christianity is not deeply personal, then it is nominal, which is unreal and no good to anyone.

Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. Romans 12:2 (ESV)
The key method Paul underscores as the means to the transformed life is by the “renewal of the mind.” This means nothing more and nothing less than education. Serious education. In-depth education. Disciplined education in the things of God. It calls for a mastery of the Word of God. We need to be people whose lives have changed because our minds have changed.
