I also like to think of it with this image. If I sit and watch my father do his work from the sidelines, I can become bored very quickly. But suppose that my father tells me as he is pushing a lawn mower or roto-tiller "Put your hand on one of the handles and push." Suddenly, this becomes an opportunity for bonding, and growing, and it is something which we are doing together. In truth, I am not pushing very hard, even though I am pushing with all my might. My dad is providing the real power, but I am now invested. I am cooperating. I am joined with Him. I can become like Him by sharing in what He is doing. He can empower Me to Grow into His full stature. But it is Him doing the work in which I am sharing.
To worship God is to honor all the work that He has done. This includes the work which He has completed in the Saints who have passed into Glory before us. If they have become Holy, it is only because He Who Is Holy has worked His Holiness in them. He has Transformed them. He has Transfigured them. They didn't let this happen in a passive manner, however. They opened themselves up to His work. They said Yes. They grew in Love of Him and of their neighbor. And once they passed into Glory, they did not stop loving their neighbors. They continued. Part of Love is to assist in the provision for the good of the ones who are beloved. They could not be said to love if that stopped once they arrived in heaven, nor could they be said to love God if they did not love their neighbor once they arrived in heaven. Therefore, they must continue to communicate with us by joining us when we pray, and for us by their prayers on our behalf. This is the only way that heaven could possibly be. Therefore, when we ask the intercession of saints out of our love for them who are our neighbors, and they intercede for us in their love for God, it is not worship being given to the saints, but the natural life of the Church of God in action, whereby love is being shown within a community whose worship is directed whole heartedly at God, in love of neighbor and of self.
God is glorified in His saints; all of them without exception. By not honoring them, we deny Him the worship which He deserves, for they are His workmanship.
