1 Thessalonians 5:16-18
Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you.  

“How can I know God’s will?” So often, these words escape from the lips of those who follow Christ. Yet it is not God’s will that is unknown as often as it is our unwillingness to search for it in his Word. We tend to think it would be easier if we could hear a fresh, new instruction from God each time we needed guidance rather than have to study Scripture.

Yet, in these three brief verses, we are given specific instructions concerning God’s will for us. If we would become disciplined in these three areas, not only would we live in a manner more pleasing to Him, but we would find ourselves wondering what His will is less and less.

First, we are to rejoice always. How many people have been turned away from the Gospel because of the dour expressions of Christians? For what reason should a believer douse the joy of God’s salvation; nothing can ever separate us from the love of God in Christ Jesus our Lord, therefore nothing in this world – be it trial, trouble, or temptation – is strong enough to quench our joy. Certainly, some days are more pleasant that others, but the joy of the Lord is not based on externalities. Instead, it comes from an absolute assurance in the person and work of Christ.

Secondly, we are to pray continually. Remember that prayer is not just talking to God, but also listening to Him. We must continually be sensitive to the work of His Spirit in our lives, ready to obey as He prompts us to speak or act. Our hearts and minds should "without ceasing" be centered on the redeeming work of Christ and the eternal promises of God, confident in His power and dependant solely on His grace.

Thirdly, we are to give thanks in all circumstances. While it may seem difficult to give thanks during difficult times, we are to do so. No matter what may come against us, it is God who sustains us and strengthens us, and brings us through. As Charles Spurgeon said: “The deeper our troubles, the louder our thanks to God, who has led us through them all and preserved us until today.”

Let us be ever mindful that the Father has gone to great lengths to provide instruction for us concerning His will for our lives. And as people who have received such a great revelation, “let us hold true to what we have attained.” [Philippians 3:16]
