Does the inner working of the Father in us eliminate our responsibility to participate in Christ being at home in our hearts?
No. God’s work within us does not eliminate our responsibility to trust the Lord. Jesus is at home in our hearts through faith (Eph. 3:17). And when we come to faith in Christ as our Lord and Savior, we are to continue to live our lives by placing our trust in Him.
We should not put our trust in our feelings nor in our internal impressions, but only in Jesus, based on His Word. Faith that takes the Lord at His Word unlocks the door of our hearts and opens it wide for Christ to make His home in us.
