John Nelson Darby emphasizes the importance of communion with God as the source of true strength and peace, encouraging believers to trust in God's faithfulness while navigating the challenges of life. He highlights the necessity of faith in being a pilgrim on earth and the importance of following the light of truth that God provides. Darby reassures his brother that true liberty and joy come from serving the Lord and maintaining a close relationship with Him, urging him to remain steadfast in faith and to seek God's guidance in all matters.

p51 [E Maylan] [From the French.] DEAR BROTHER, - Dear F. has communicated to me your letter. I bless God that you have found the sweet peace of communion with God: it is there that strength is found - our only true strength; it is there, dear brother, that we get hold of, and there alone, the principles which make us pilgrims and strangers here below, because faith is in question when one desires to be a stranger on earth, and to lean only upon God. Happy, thrice happy, he who can do it, but this can be only through communion. And now, whilst encouraging you, and ready to help you, so far as the Lord will enable me, I urge you to weigh the matter well, and to see if with ten thousand you are able to make war against him who comes against you with twenty thousand; if not (it is God who makes all the difference) you must make peace, and be content, if you have peace, to remain on this side of Jordan, instead of trusting to God that which is dear to you, and going to make war against those who still hold the land. But I believe that you have tasted too much what truth is to act thus: you have too much light to be on good terms with God in not following this light. God has acted, dear brother, with respect to you, with so much goodness and tenderness in leading you into His work, and in following you along the road, that I hope your heart will feel its effects powerfully. As for me, I will do what I can to help you, as every brother in Christ. God has stood by you, when you had only Himself and the resources which He Himself placed at your disposal, so that there is enough to lead you to trust His faithfulness. . . . I say no more, except that I shall be rejoiced to see you walk with liberty in the path of truth and of personal devotedness. I know by my own experience, that those who trust in the Lord shall not be confounded, and that His service is the only true liberty and joy on earth. I commend you heartily to Him; He is the only resource that you and I have. I rejoice at the peace and the healthy condition of your soul, as if it were myself. Let us remember that communion is a matter of eternity, this sweet and precious eternity which Christ has won for us, of which He Himself will be the centre and the glory. Adieu, dear brother; peace be with you, keep yourself in the love of God, and look only to Him: if your eye is single, your whole body shall be full of light. There is much blessing in Switzerland, but a little commotion, because of the new wine, which does not suit well with the old bottles - old at least in many respects, because they are human - and everything is feared about if anything is touched. Your affectionate brother. I shall be at Lausanne probably next week. Lausanne, October 10th, 1842. [51026F]
