I. It is not easy to determine in which of two senses the former clause is to be taken. The Lord is near in position, and the Lord is near in approach. In either sense we can connect the doctrine and the precept. If the Lord is soon coming, how idle must be all anxiety about things soon to be dissolved; if the Lord is always present, how needless must be all anxiety about things easy of remedy. The two thoughts fall into one. But it is with the latter of the two that I desire to occupy you now. The Lord Jesus Christ is always at hand; therefore turn all anxiety into prayer. Thousands of hearts have found repose in this one word of inspiration. Towards some verses we cannot but feel as we do towards a place ennobled or consecrated by the footsteps of saints or heroes. Such verses have a history as well as a doctrine, and is not this one of them? The Lord is ever near, not more in the approach of His advent, than in the reality of His spiritual power. Wherever, in perfect solitude or amidst the din of uncongenial sounds, one humble heart turns to Him as the Saviour and the Intercessor, there is He, not to be sought far and found late, but listening before speech, answering before entreaty. Whatever we be, He changes not; if we doubt His presence, we disparage His power, we deny His Divinity.
II. Be anxious about nothing. Anxiety is (1) an idle thing: (2) an enfeebling thing; it eats the very life out of the energies; it leaves the man, not only where he was, but ten times less capable and less vigorous than at the beginning: (3) an irritating thing; it ruffles the temper; it upsets the balance of the spirit; it is the sure source of moodiness, and sharpness, and petulance, and anger; it sets a man at war with himself, with his neighbour, with God's providence and God's appointments. Anxiety is a sign of mistrust; a sign of feeble faith, of flagging energy, and languid obedience. In Christ's presence, in His human soul, in His compassionate heart, we may lay aside our anxieties, we may rest from our burdens, and we may take refuge from our fears and from our sins.
