God's purposes and promises change not, therefore our faith may rest on Him, notwithstanding our own sins and fluctuations. It is this aspect of the divine immutability which is the thought of our text. God does not turn from His love, nor cancel His promises, nor alter His purposes of mercy because of our sins. If God could have changed, the godless forgetfulness of, and departure from, Him of 'the Sons of Jacob' would have driven Him to abandon His purposes; but they still live--living evidences of His long-suffering. And in that preservation of them God would have them see the basis of hope for the future. So this is the confidence with which we should cheer ourselves when we look upon the past, and when we anticipate the future. The sins that have been in our past have deserved that we should have been swept away, but we are here still. Why are we? Why do we yet live? Because we have to do with an unchanging love, with a faithfulness that never departs from its word, with a purpose of blessing that will not be turned aside. So let us look back with this thought and be thankful; let us look forward with it and be of good cheer. Trust yourself, weak and sinful as you are, to that unchanging love. The future will have in it faults and failures, sins and shortcomings, but rise from yourself to God. Look beyond the light and shade of your own characters, or of earthly events to the central light, where there is no glimmering twilight, no night, 'no variableness nor shadow of turning.' Let us live in God, and be strong in hope. Forward, not backward, let us look and strive; so our souls, fixed and steadied by faith in Him, will become in a manner partakers of His unchangeableness; and we too in our degree will be able to say, 'The Lord is at my side; I shall not be moved.' A DIALOGUE WITH GOD 'Return unto Me, and I will return unto you, saith the Lord of Hosts. But ye say, Wherein shall we return?'--MALACHI iii. 7 (R.V.). In previous sermons we have considered God's indictment of man's sin met by man's plea of 'not guilty,' and God's threatenings brushed aside by man's question. Here we have the climax of self-revealing and patient love in God's wooing voice to draw the wanderer back, met by man's refusing answer. These three divine utterances taken together cover the whole ground of His speech to us; and, alas! these three human utterances but too truly represent for the most part our answers to Him. I. God's invitation to His wandering child.
