“¶For the grace of God has appeared, bringing salvation to all men, instructing us that, denying ungodliness and worldly desires, we should live sensibly, righteously, and godly in the present age,” Titus 2:11-12 LSB

Salvation has come that people might live sensibly. Paul uses this word in this translation multiple times. What does it mean to live sensibly? Webster originally defined sensible as ‘having the capacity of receiving impressions from external objects.’ Paul uses the word to mean under the authority of God. We are sensible when we understand that God is the Author of our salvation, the Purchaser of our lives from condemnation, and thus the Lord over us, so we now live under His rule. It is sensible for the man of God to live as one controlled by the ways of God as given to us in the word of God. This is the sensible life that Paul says older men should model and younger men and women should live as Christian examples to the world. We are sensible and right-minded when God’s ways determine our thinking and behaving, not the ways of the world or our fleshly desires. The result of living by God’s standards and commands is that we show ourselves to the world as righteous and godly, for we no longer do those things that displease God but the things for which God is well pleased and glorified among men. If we are truly saved and genuinely Christian, then we will live as sensible people who study God’s word to obey God’s ways, for they are the good, right, and accurate ways we are to live.
