Our redemption is the work of our triune God: planned by the Father, accomplished by the Son, and applied to us by the Holy Spirit. Today, R.C. Sproul considers the work of the Trinity in salvation.
Not only is creation a Trinitarian work, but redemption is also a Trinitarian work. The Father is the One who initiates the concept of redeeming a creation that He knows will be fallen. And so, it is the Father who designs the plan of redemption. It is the Son who is given the assignment by the Father to accomplish that redemption. And of course, it is the work of the Holy Spirit to apply that work of redemption to us. But we have to understand that this does not represent a struggle within the Godhead itself, but rather an eternal agreement. The Son is sent by the Father, and the Son is absolutely delighted to be sent and to carry out the mission that the Father has given to Him.
