When a Christian is weak, and can hardly pray for himself, Jesus Christ is praying for him; and he pray for three things.
First, that the saints may be kept from sin (John 17:15). “I pray that thou shouldest keep them from evil.” We live in the world as in a pest-house; Christ prays that his saints may not be infected with the contagious evil of the times.
Second, for his people’s progress in holiness. “Sanctify them” (John 17:17). Let them have constant supplies of the Spirit, and be anointed with fresh oil.
Third, for their glorification: “Father, I will that those which thou hast given me, be with me where I am” (John 17:24). Christ is not content till the saints are in his arms. This prayer, which he made on earth, is the copy and pattern of his prayer in heaven. What a comfort is this; when Satan is tempting, Christ is praying! This works for good.
