Therefore, having these promises, beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God. (2 Corinthians 7:1)
Filthiness is the corruption of morals, principles or character; impurity; pollution by sin.
Therefore, having these promises
The promises are those which close the prior chapter. They include promises of God's presence, God's protection and God’s provision. They include the privilege of being His temple, His people, and His children. Such goodness from the Lord encourages Holy living.
For indeed, when we came to Macedonia, our bodies had no rest, but we were troubled on every side. Outside were conflicts, inside were fears. (2 Corinthians 7:5)
When there is fear inside a person, such a person cannot have proper rest in mind and body. Rest for the body comes when we have peace on the inside.
But God, Who comforts and encourages and refreshes and cheers the depressed and the sinking, comforted and encouraged and refreshed and cheered us by the arrival of Titus. (2 Corinthians 7:6 Amplified)
Comforts, encourages, refreshes and cheers the depressed and the sinking. God often does this by sending a man of God into your life
Now I rejoice, not that you were made sorry, but that your sorrow led to repentance. For you were made sorry in a godly manner, that you might suffer loss from us in nothing. For godly sorrow produces repentance leading to salvation, not to be regretted; but the sorrow of the world produces death. (2 Corinthians 7:0-10)
The world today wants nothing to do with sorrow. The world has its music, therapies, medications, alcohol, and the like; all designed to numb your sorrow
If it makes me sad, it must be bad! is a maxim to which we seem to adhere by default. But sorrow can be beneficial; it is not always a bad thing. Paul writes to the Corinthians that, though he did initially, he does not regret having caused them sorrow (2 Corinthians 7:8) because they were made sorrowful to the point of repentance, according to the will of God (2 Corinthians 7:9).
This verse makes clear that there is a kind of sorrow that is according to the will of God. There is a sorrow that God wants you to experience, because the sorrow that is according to the will of God “produces a repentance without regret, leading to salvation” (2 Corinthians 7:10). Paul is teaching the Corinthians that an essential component of true repentance is genuine sorrow over having grieved God and belittled His holiness.
because his spirit has been refreshed by you all. (2 Corinthians 7:13)
Good fellowship can refresh a person’s spirit.
