Sure, OR, He loves all the sinful people of HIS kingdom this way...iow, He is telling His listeners how to act, not necessarily precisely defining the children as innocent of sin ie not under the consequences for sin, suffering and death, but as merely trusting and compliant, not yet hardly leavened by sin at all, 1 Cor 5:8, Matt 16:6&12, pointing to the familial and ordinary experience of young children, not the theology of their creation and fall.So we learn from Jesus' indignation, first, that Jesus loves children, and, secondly, that Jesus affirms and respects the personhood and spirituality of children.In saying, "for to such belongs the kingdom of God," he affirms their full spirituality. They are the hearts he takes to himself! Christ affirms and proclaims the spiritual capacity of children.
But it does NOT explain the knowledge the twins had about their existence and their future in that existence.
