And the angel of God, which went before the camp of Israel, removed… – Exodus 14:19 

For ye shall not go out with haste, nor go by flight: for the LORD will go before you; and the God of Israel will be your rereward. – Isaiah 52:12

“The Lord will go before you, and the God of Israel will be your rereward.” This is the condition into which the Lord brings His people when they depart from Babylon and are no more conformed to this present evil world. I trust He has brought many of us into this all-surrounding light at this good hour. The Lord is behind us, we know: our sins and iniquities are covered, our past mistakes are all erased, we are accepted in the Beloved. But we have not to look forward and say, “The Angel of God has removed.” Oh, no. We can see the bright light before us still. Our ways are ordered of the Lord, and none of our steps shall slide. We glory in tribulations also, believing that we shall glorify God in them. We look forward to the time of old age, believing that to hoar hairs He is the same, and that in our days of decline He will carry us. We look forward to the advent of our Lord with delight; or, if that may not be in our day, we look to falling asleep upon the bosom of our Savior. Before us we see the resurrection morning and all its splendor: we anticipate the risen body, that glorified fabric in which our pure and perfect spirits shall dwell for ever: we hear the voice of harpers harping with their harps, saluting the reign of Christ and the glorification of His people with Him. Below there is nothing before us now but that which is inexpressibly delightful: the day has long dawned with us, whose morning clouds have passed away; a day which grows warmer and brighter and is nearing to the perfect day. A few more months, a few more years, and we shall be in the land of the unclouded sky. What will it be to be there! What will it be to be there for ever! How willingly would I fly away and be at rest. I feel my wings; they are not strong enough, as yet, to bear my soul away; but they will be. God is making His children ready to depart, and He will only have to beckon them, and they will cry, “Here am I,” and then they shall be with Him for ever. ~ C.H. Spurgeon
