Paul is a model for all believers, especially preachers.  Here he lists our weapons, such as preaching and witness, to be maintained regardless of our reception, even despite great violence, and through lows and highs - making many rich, and though having nothing, yet possessing all things.

Here are our three greatest mistakes about God that keep us from seeking Him, and here also are the three charges that God will bring against us if we ignore Him in our lives.  Best of all, here is God's way of forgiveness and real life.

An unbelieving world, says Isaiah, will be deaf to the message behind God's mighty events (whether conquest or pandemic) while believers will know His love and power, and reap a great spiritual harvest. Here we explore the prophet's powerful words and their fulfillment.

The apostle gives inspired and essential conditions for instrumentality in Gospel work.  Beginning with a strong plea to avoid fruitlessness, he stresses the necessity of a consistent life, resilience through all hardship, and five positive qualities which must be exhibited, by the Spirit's help.

In this prophecy of the church age Isaiah demonstrates the challenging character of Gospel preaching, first stressing the obviousness of God, then His sovereign rule throughout history, and finally the rewards of faith and prayer - especially the power and strength imparted by Him.

These verses reveal first the means by which Paul sustained his unflagging zeal; secondly the radical change of outlook brought about by conversion, and thirdly the compelling obligation for evangelism which is given to every true believer: are we really saved, and are we genuine witnesses?
