13  So I ask you not to lose heart [not to faint or become despondent through fear] at what I am suffering in your behalf. [Rather glory in it] for it is an honor to you.14  For this reason [seeing the greatness of this plan by which you are built together in Christ], I bow my knees before the Father of our Lord Jesus Christ, 15  For Whom every family in heaven and on earth is named [that Father from Whom all fatherhood takes its title and derives its name].16  May He grant you out of the rich treasury of His glory to be strengthened and reinforced with mighty power in the inner man by the [Holy] Spirit [Himself indwelling your innermost being and personality].

Paul asked the Ephesians not to lose heart because of what he was suffering for them. Paul counted it an honor to suffer for God. He wanted  others not to feel sorrow for him, but to understand that it was an honor to suffer for the name of Christ.

V16, Paul prayed that God, out of all the riches of his account of glory, the gives the people strength and reinforcement with the mighty power of the inner man. This strength and reinforcement is brought about by the Holy Spirit. God uses the Holy Spirit to interwork with the people by communicating with their Spirit and working with their personality.

So God will, according to V16, possibly do two things in us: He will bring strength and be reinforced with mighty power in the inner man. I want so badly that my inner man is reinforced with mighty power.

God will not leave us in our trials, but will provide strength. This strength is nothing like the strength of the natural. This strength could come in the form of a filter around us that we can sense. A filter of peace, wherein all things incoming must pass through this filter before we get it. It is a sense of contentment which is worth more than anything. If a person is content, his life is more at peace. God can provide contentment to us when we follow Him. He has the power to alter us at the very core. No more chasing things we cannot afford, but we are happy with the things we have.
