But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man who looks intently at his natural face in a mirror. For he looks at himself and goes away and at once forgets what he was like. But the one who looks into the perfect law, the law of liberty, and perseveres, being no hearer who forgets but a doer who acts, he will be blessed in his doing.

If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person's religion is worthless. Religion that is pure and undefiled before God, the Father, is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world. (ESV)

The Gospel: St. John 16:23b-33

Dietrich Bonhoeffer wrote of "easy believism" and that is what today's Epistle addresses.  While we are saved sola gratia -- because of grace alone -- we are not saved by a grace that is alone.  We need to put feet to our faith and live it out by showing forth God's grace as we live lives transformed my His grace.  As the Twelfth Article of Religion states:

Albeit that Good Works, which are the fruits of Faith, and follow after Justification, cannot put away our sins, and endure the severity of God's judgment; yet are they pleasing and acceptable to God in Christ, and do spring out necessarily of a true and lively Faith; insomuch that by them a lively Faith may be as evidently known as a tree discerned by the fruit.

We need to be doers of the Word who respond in faith to the Gospel and bear fruit.  We do so not to "earn" our salvation (we can never do that) but to glorify Him who gave Himself so that we who were dead in our trespasses and sins so that we might receive the adoption of sons and have eternal life.
