…unto Thee shall the vow be performed. – Psalm 65:1

We are not given to vow-making in these days. Time was when it was far oftener done. It may be that had we been better men we should have made more vows; it may possibly be that had we been more foolish men we should have done the same. The practice was so abused by superstition, that devotion has grown half-ashamed of it. But we have, at any rate, most of us bound ourselves with occasional vows. I do confess to-day a vow I have not kept as I should desire; the vow made on my first conversion. I surrendered myself, body, soul, and spirit, to Him that bought me with a price, and the vow was not made by way of excess of devotion or supererogation, it was but my reasonable service. You have done that. Do you remember the love of your espousal, the time when Jesus was very precious, and you had just entered into the marriage bond with Him? You gave yourselves up to Him, to be His for ever and for ever. O brethren and sisters, it is a part of worship to perform that vow. Renew it, make another surrender of yourselves to Him whose you are and whom you serve.

Beloved, many of us did, in effect, make a most solemn vow at the time of our baptism. We were buried with Christ in baptism unto death, and, unless we were greatly dissembling, we avowed that we were dead in Christ and buried with Him; wherein, also, we professed that we were risen with Him. Now, shall the world live in those who are dead to it, and shall Christ’s life be absent from those who are risen with Him? We gave ourselves up there and then, in that solemn act of mystic burial. Recall that scene, I pray you; and as you do it blush, and ask God that your vow may yet be performed, as Doddridge well expresses it:-

“Baptised into your Saviour’s death
Your souls to sin must die;
With Christ your Lord ye live anew,
With Christ ascend on high.”
~ C.H. Spurgeon
