In his short essay, “Christian Doctrine and Life,” The theologian John Murray stressed that the great doctrines of the Christian life have implications for everyday life.
Consider these texts:
 But it shall not be so among you. But whoever would be great among you must be your servant,  and whoever would be first among you must be slave of all.  For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.” Mark 10:43-45
 For to this you have been called, because Christ also suffered for you, leaving you an example, so that you might follow in his steps. 1 Peter 2:21
Elsewhere, I have given a brief overview of systematic theology for our church family. But one thing that we must never lose sight of is that even though doctrine may stretch our intellect and vocabularies, it is not in any sense removed from every day life. John Murray beautifully explains this point. Here are a few excerpts he makes relative to the above Bible texts and others as well:
“It is worthy of note that some of the most characteristic definitions of Christ’s atoning accomplishment are given in appeals to believers to practise the most elementary duties of their heavenly vocation.” cf. (Matt 20:28, Mark 10:43-45).
“And the great lesson for our present interest is that there is a direct connection between the most sacred truths of our faith and the most elementary duties of our Christian calling. The great truth of the atonement, than which nothing is more central, is the incentive to humble, devoted, self-sacrificing service in the kingdom of God.”
“There is a straight line of connection between the death of Christ and elementary virtues of the Christian life.”
