Not only did God send Christ to die for our sins and sanctify us, but He also sent the Holy Spirit to bear “witness” to us, so that the His righteous laws might be written on our hearts and minds. It is by believing in Christ Jesus that we are saved. And it is by the Holy Spirit that we are assured of our salvation. For the Spirit is the inner witness that gives us the awareness of our adoption as children of God, so that we call Him “Abba, Father” (Rom.8:15-16). It is through His inner witness that our hearts and minds are continually sanctified, so that we love God as Father and desire to do His will.
