Matthew 26:39 seems to imply that Christ’s human will natively resisted death but capitulated to the divine will in submitting to the cross. However, this understanding seems suspect. Even if one concludes that there are, indeed, two wills in Christ, there surely is no volitional conflict in the person of Christ. Both as human and divine Christ had but one direction in moral decisions—to do his Father’s will (Heb. 10:7). I am inclined to view Matt 26:39 not as a tug of war between independent or conflicting moral/volitional impulses in the person of Christ, but as idiomatic of the God-man’s singular wish for an alternative to the horror he was about to experience.
This text aside, then, the question that emerges is whether self-determination resides in the nature or in the person. If self-determination resides in the nature, then Christ had two wills that were absolutely non-conflicting and perfectly harmonious in every way. If the latter then Jesus, as a single person, has but one self-consciousness and one self-determination. While both views have merit, it seems easier to say that Jesus had one will as an indivisible person (See A. H. Strong, Systematic Theology, 694–96).
