No need. I think it’s understood that you do indeed receive something when you go to an altar call. In addition to giving yourself over to the Lord you do profess that the Holy Spirit is received.
PRmerger—Yes, in any relationship the given and receiving is mutual, and more circular than linear. IOW, I don’t conceive of giving/receiving like it’s a yardstick with giving neatly marked off at one end and receiving marked off at the other end; it’s more like a circle or sphere with both giving and receiving cycling around all the time.
But, with the revision that altar calls are primarily but not exclusively about us giving ourselves, I’ll stick with my original idea. There’s a distinct ethic, so to speak, of giving ourselves in altar calls that’s different from the receiving (“Take and eat…”) of Communion. We are nothing in ourselves, of course, and we can only return to God what He first gave us; and in the Methodist theology in which I was raised, we believe it’s God’s prevenient Grace which first moves us to respond to the offer of reconciliation and adoption which He initiates. But in altar calls, there’s a particular sense of self-surrender, self-emptying, and letting go of our attachments—why? because God is worthy of that kind of whole-hearted devotion and worship; but also
in order to be free to receive more of God’s influence. Some Evangelical hymns commonly used at altar calls show this ethic: “I Surrender All”, “Take My Life and Let It Be (Consecrated Lord to Thee)”, “Is Your All on the Altar of Sacrifice Laid”. ( There’s also a contemporary song by Clay Crosse called “I Surrender All” that’s about this self-giving ethic.)
If I were to try to give you the picture in my mind that I have for altar calls, it would be that of a person kneeling at the feet of their Lord and Master in worship and humility, while offering their upturned cupped hands to Him—handing over to Him as an offering, their heart and soul, mind and strength. We believe in His graciousness He will accept our offering and fill our hands and our very selves with more of Himself. In Communion, as an Evangelical, my picture is more of Christ surrendering Himself for us: kneeling before us in unfathomable Divine humility to wash our feet, and offering Himself on the altar to be broken for us. In altar calls, we are broken before Him.
