The Father and the Son...relationship

The Father and the Son possess a strange relationship. The Father readily elects his Son as the leader to be obeyed by all. The Son readily welcomes this responsibility. However, when conflict arises, the Father does not elect his Son but the Son humbly offers his service. The Son does not appear obligated but instead calm and confident. He is prepared to combat evil. If the Father has the keen awareness of what the future holds, did He create his Son in his likeness for this very purpose? Is this perhaps the reason that the Father does not resist the Son's offer or even consider going Himself? Where does the distinction between the Father and the Son reside if he was created and formed for these intentions? This certainly adds to the peculiarity of this divine relationship. Is it one in the same OR just divine intervention at its best?
