God has a plan – it may be, however, that we don’t see it.
God’s plan is the salvation of souls. He wants all people to be saved and to come to the knowledge of the truth. He wants to be worshiped and adored by His people. God wants His people to love and trust Him and each other. God wants to restore lost sinners to a place in heaven.
God has a plan, to be sure; but it was interrupted by Satan. The devil took on the form of a serpent, tempted Adam and Eve to sin (and succeeded), and then later on fought to keep God from reestablishing a state of grace and mercy for humankind.
God has a plan, but we may not see it now. The devil still fights God tooth and nail (so to speak), trying to stymie the work of the Holy Spirit, the Church on earth, and individual Christians so as to hinder the spread and power of the Gospel of Jesus Christ.
From this writer’s perspective this is exactly what St. Paul was considering when he wrote the words of our reading from Ephesians. God had a plan, and it is still in play! It still centers around the person and work of Jesus Christ. It is still empowered by the Holy Spirit. It is still blessed by God!
God has a plan, and it includes YOU! As Paul wrote in the concluding portion of today’s Epistle reading:
 In him we have obtained an inheritance, having been predestined according to the purpose of him who works all things according to the counsel of his will,  so that we who were the first to hope in Christ might be to the praise of his glory.  In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit,  who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.
