These two statements are paired,to reinforce the understanding that it is christ that strenthens (the holy spirit)that causes Christ to dwell. This is understood because the first part of this verse states "I pray that out of HIS glorious riches HE may strengthen you with power through HIS Spirit in your inner being, so that Christ may dwell in your hearts through faith." (3:16b-17a) HIS, HE, HIS refers to the indwelling Holy Spirit (Christ)Which we receive at baptism to do the work of empowering us which sustains (keeps Christ secure in our hearts because our faith is anchored in HIM). So, begins the second part of this verse and indicates as a result of this, HE dwells (present tense). HIS presence (Christ)is secured in us. These 2 concepts are not seperate and distinct ideas but one conveying the idea that it is the fullness of Christ that every believer would have for which Paul prays.
