In his letters to the Ephesians, Paul says, “Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.” And then he adds: “And grieve not the Holy Spirit of God, whereby ye are sealed unto the day of redemption. Let all bitterness, and wrath, and anger, and clamour, and evil-speaking, be put away from you, with all malice. And be ye kind one to another, tender-hearted, forgiving one another, even as God for Christ’s sake hath forgiven you. Be ye therefore followers of God, as dear children; and walk in love, as Christ also hath loved us, and hath given Himself for us” (Eph. iv. 29-v. 2).

What does Paul teach us here? That it is not by some huge wickedness, some Judas-like betrayal, some tempting and lying to the Holy Ghost, as did Ananias and Sapphira (Acts v. 1-9), that we grieve Him, but by that which most people count little and unimportant; by talk that corrupts instead of blessing and building up those that hear, by gossip, by bitterness, and uncharitable criticisms and fault-findings. This was the sin of the elder son when the prodigal returned, and it was by this he pierced with grief the kind old father’s heart.

By getting in a rage, by loud, angry talking and evil-speaking and petty malice, by unkindness and hard-heartedness and an unforgiving spirit, we grieve Him. In a word, by not walking through the world as in our Father’s house, and among our neighbours and friends as among His dear children; by not loving tenderly and making kindly sacrifices for one another, He is grieved. And this is not a matter of little importance. It may have sadly momentous consequences.

It is a bitter, cruel, and often an irreparable thing to trifle with a valuable earthly friendship. How much more when the friendship is heavenly? when the Friend is our Lord and Saviour, our Creator and Redeemer, our Governor and Judge, our Teacher, Guide, and God? When we trifle with a friend’s wishes—­especially when such wishes are all in perfect harmony with and for our highest possible good—­we may not estrange the friend from us, but we estrange ourselves from our friend. Our hearts grow cold toward him, though his heart may be breaking with longing toward us.

The more Saul ill-treated David, the more he hated David.

Such estrangement may lead, little by little, to yet greater sin, to strange hardness of heart, to doubts and unbelief, and backslidings and denial of the Lord.

The cure for all this is a clean heart full of sweet and gentle, self-forgetful, generous love. Then we shall be “followers of God as dear children,” then we shall “walk in love as Christ loved us, and gave Himself for us.”

But there is another offence, that of quenching the Spirit, which accounts for the comparative darkness and deadness of many of God’s children.

In I Thess. v. 16-19 the Apostle says: “Rejoice evermore. Pray without ceasing. In everything give thanks: for this is the will of God in Christ Jesus concerning you. Quench not the Spirit.”

When will the Lord’s dear children learn that the religion of Jesus is a lowly thing, and that it is the little foxes that spoil the vines? Does not the Apostle here teach that it is not by some desperate, dastardly deed that we quench the Spirit, but simply by neglecting to rejoice and pray, and give thanks at all times and for all things?
