Philip consulted with Andrew, and the two men told Jesus. Read today, the Lord's response seems startling. Jesus did say that anyone who wants to serve Him must follow Him. Even Jesus had to learn obedience. If sanctification is becoming like Christ, then we must walk the way Jesus walked, by the way of Gethsemane and Calvary.
Sanctification involves death, death to self, death to the ego.
God the Father is actively involved by exercising His divine discipline. Moreover, we have all had human fathers who disciplined us and we respected them for it. No discipline seems pleasant at the time, but painful. Here is grace operating in the form of divine discipline. Christlikeness, holiness, godly living, are produced in us by the Holy Spirit as we submit in faith to the Father's discipline.
