The gracious invitation of our text presupposes a state of departure. The child who is tenderly recalled has first gone away. There has been a breach of love.
Dependence has been unwelcome, and cast off with the vain hope of a larger freedom in the far-off land; and this is the true charge against us. It is not so much individual acts of sin but the going away in heart and spirit from our Father God which describes the inmost essence of our true condition, and is itself the source of all our acts of sin. Conscience confirms the description. We know that we have departed from Him in mind, having wasted our thoughts on many things and not having had Him in the multitude of them in us. We have departed from Him in heart, having squandered our love and dissipated our desires on many objects, and sought in the multiplicity of many pearls--some of them only paste--a substitute for the all-sufficient simplicity of the One of great price. We have departed from Him in will, having reared up puny inclinations and fleeting passions against His calm and eternal purpose, and so bringing about the shock of a collision as destructive to us as when a torpedo-boat crashes in the dark against a battle-ship, and, cut in two, sinks.
The gracious invitation of our text follows, I am the Lord, I change not; therefore ye sons of Jacob are not consumed.' Threatenings, and the execution of these in acts of judgment, are no indication of a change in the loving heart of God; and because it is the same, however we have sinned against it and departed from it, there is ever an invitation and a welcome. We may depart from Him, but He never departs from us. Nor does He wait for us to originate the movement of return, but He invites us back. By all His words in His threatenings and in His commandments, as in the acts of His providence, we can hear His call to return. The fathers of our flesh never cease to long for their prodigal child's return; and their patient persistence of hope is but brief and broken when contrasted with the infinite longsuffering of the Father of spirits. We have heard of a mother who for long empty years has nightly set a candle in her cottage window to guide her wandering boy back to her heart; and God has bade us think more loftily of the unchangeableness of His love than that of a woman who may forget, that she should not have compassion upon the son of her womb.
