It is a good and gracious thing that your heart is burdened to pray for your friends who come but sporadically to the house of God. Such intercession is itself a work of love, and the Lord who puts it into your heart will hear it. We ought to pray constantly for one another, and the fire upon the altar of intercession should never go out, neither by night nor by day.
You desire that they should return, and this is the very voice of God Himself to every wandering soul. Hear how tenderly He cries, Return, return. He says, Return, ye backsliding children, and I will heal your backslidings, for I am married unto you. It is not a harsh command but a gracious summons, spoken by One who is still married to His people and who has forgiveness and mercy yet in His heart. While you hear your Lord saying Return, return, it will help them to return if they remember those halcyon days when their hearts had a whole peal of bells within, sounding the richest melody to the praise of Christ.
Think also of the dove which went forth from the ark and found no rest for the sole of her foot until she returned. So it is with every soul that flies abroad from Christ and from His church. It may take its survey of all things, but it finds no rest anywhere except in Christ Jesus. However long the flight, the weary soul must come back to its proper resting place, for no other pasture is green enough and no other refuge will hold. Pray that your friends may feel this unrest and be drawn back to Him in whom alone there is rest.
Do not grow weary though they did not attend the Bible study and seem slow to change their minds. The Lord adds to the church daily such as should be saved, and one reason the early church had such blessing was because her members were a praying church and had such homes of prayer. Give no rest to your eyes, nor slumber to your eyelids, till you have pleaded for them, and continue to invite them with gentle and earnest love. Speak to them when the Lord gives opportunity, not with contention but with the kindness that would have them run so as to obtain.
Let us pray together for them.
O Lord our God, we bring before Thee these friends who have wandered and who come but seldom to Thy house. Thou knowest their names and Thou seest their hearts. We ask Thee to lay upon them the sweet constraint of Thy love, that they may hear Thy voice saying Return, return, and may answer, Behold, we come unto Thee. Heal their backslidings, forgive their wanderings, and draw them again to Christ, in whom alone is salvation. Grant them to find no rest apart from Him, but to return as the dove to the ark, to find safety and peace. Add them, we beseech Thee, to the number of those who love Thy house and delight in Thy word, and give our dear friend who prays for them wisdom and patience to speak a word in season. For Thy glory and for their eternal good we ask it, in the name of Jesus Christ our Lord. Amen.
