2 Corinthians 1:12

For our rejoicing is this, the testimony of our conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God, we have had our conversation in the world, and more abundantly to you-ward.

True rejoicing is the testimony of the conscience that conduct has been in simplicity and godly sincerity and honesty. That testimony concerns having had conversation in the world, and more abundantly toward fellow believers at Corinth, not by human or fleshly wisdom and not by plans of human devising, but by the grace of God. Paul's ministry embodied this, for by God's grace he served faithfully and honestly with simplicity and purity in the Spirit. He did not rely on natural eloquence and did not seek human praise or honor or a reputation for wisdom, but aimed at the good of souls. He used God-given wisdom to lead people from error and superstition and to strengthen the churches in the faith, so that he had not been dishonest or unfaithful and no valid charge of dishonesty or unfaithfulness could be made against him.

Its setting is the wonderful blessing that attended the liberality of the early Christian church, joined with steadfast hope that as believers share sufferings they also share comfort and consolation, and with helping together by prayer so that the gift bestowed through many persons brings thanksgiving to God by many. Unselfish liberality threw the early church into joy, even into a transport of joy, because members knew God's power was being carried and borne to the needy, and their active kindness and benevolent energy proved and testified that they had not received God's grace in vain. Such liberality is produced only by sanctification of the Spirit through the Word, and in the eyes of believers and unbelievers it is a miracle of grace. It calls for watching, standing fast in the faith, acting with strength, and doing all things with charity.

God's ministers are to stand in a high and holy position in simplicity and godly sincerity. This requires self-denial, eating simple food that leaves the brain clear, and keeping the body in the best condition of health in order to recommend the truth. It requires judging righteously and voicing the words of God, practicing practical godliness, and keeping clear discernment to speak under the influence of the Spirit because Christ is present in every assembly, while guarding the lips against anything that brings disturbance. Conduct in the world and toward others is to be marked by simplicity and humility and godly sincerity through reliance on God's grace rather than human wisdom. In God's service simple plans avoid the confusion of man-made additions and accomplish more, and simplicity and humility characterize effective efforts to advance His kingdom.

Life is to be lived in simplicity and Godlike sincerity, not with fleshly wisdom but by the grace of God, with the wisdom that comes from above and with Christian experience animated by piety and instinct with divine life. Accepting God's blessings in this way brings righteousness and peace, whose fruit is quietness and assurance forever, removing the disquietude of uncertainty. It means worshiping the Lord in the simplicity of true faith and true godliness by trusting in God, believing His Word with simple confiding faith, and living continually upon His gracious promise with encouragement in the Lord.
