Here's what I see when I read this passage for myself :
26) Likewise ( referring to what came before in the chapter ), the Spirit helps our infirmities ( physical conditions of the flesh ), because we do not know what we should pray for as we ought to.
But the Spirit within us makes intercession for us with groanings that cannot be spoken by us.
27) He that searches the hearts ( that's the Lord, please see Psalms 44:21, Psalms 139:1, Jeremiah 17:10, Acts of the Apostles 1:24 ), knows what is the mind of the Spirit ( for they are One, please see 1 John 5:7 )...
Because He ( Christ ) makes intercession for the saints ( Romans 8:34, Hebrews 7:25 ) according to God.
28) We know that all things work together for good to them ( individuals ) that love God.
They are the same people who are "the called" according to purpose.
29) Those ( individuals ) He foreknew, He did many things for...
Firstly, He predestinated them to be conformed to the image of His Son, so that His Son would be the firstborn among many brethren.
30) Plus, those ( individuals ) He predestinated to be conformed to the image of His Son, He also "called".
Those ( individuals ) that were "called" He also justified.
Those ( individuals ) that He justified, He also glorified.
