Pray without ceasing. – 1 Thessalonians 5:17

Why should we obey this precept? Of course we should obey it because it is of divine authority; but, moreover, we should attend to it because the Lord always deserves to be worshipped. Prayer is a method of worship; continue, therefore, always to render to your Creator, your Preserver, your Redeemer, your Father, the homage of your prayers. With such a King let us not be slack in homage. Let us pay Him the revenue of praise continually. Evermore may we magnify and bless His name. His enemies curse Him; let us bless Him without ceasing. Moreover, brethren, the spirit of love within us surely prompts us to draw near to God without ceasing. Christ is our husband. Is the bride true to her marriage vows if she cares not for her beloved’s company? God is our Father. What sort of a child is that which does not desire to climb its father’s knee and receive a smile from its father’s face? If you and I can live day after day and week after week without anything like communion with God, how dwelleth the love of God in us? “Pray without ceasing,” because the Lord never ceases to love you, never ceases to bless you, and never ceases to regard you as His child.

“Pray without ceasing,” for you want a blessing on all the work you are doing. Is it common work? “Except the Lord build the house, they labor in vain that build it.” Is it business? It is vain to rise up early and sit up late, and eat the bread of carefulness, for without God you cannot prosper. You are taught to say, “Give us this day our daily bread,”-an inspired prayer for secular things. Oh, consecrate your seculars by prayer. And, if you are engaged in God’s service, what work is there in which you can hope for success without His blessing? Pray, therefore, as long as you work. ~ C.H. Spurgeon
