The Spirit Himself testifies together with our spirit that we are God's children,Romans 8:16(HCSB)
Man is made up of body, soul and spirit and the human spirit of man is that inner part of our being that communes with the Father and only believers have a living regenerated spirit that can have fellowship with the Father and abide in Christ – for unsaved man remains spiritually dead in trespasses and sins, without God and without hope in the world.
The indwelling Holy Spirit of God was given to each regenerated child of God at the moment of rebirth. He took up permanent residence within the heart of all those that believe on the Lord Jesus Christ and we are being built into the temple of God – created with living stones, as Christ’s witnesses to the world.
When we live and move and have our being to the glory of God, in submission to the Holy Spirit and with Christ as our central delight and joy, the indwelling Spirit of Christ DWELLS in our heart as we ABIDE in Him and REST in His love.
It is as we dwell in Him and abide in Christ that we fellowship with the Father and commune with His Holy Spirit, Who bears witnesses with our human spirit and that we are children of God. What wonderful wisdom of God that the Spirit of Christ can give such beautiful reassurance with our regenerated human spirit,
We do not need outwards signs; visible proofs or audible evidences of His presence in our heart; His promises in the Word of His saving work of grace in our lives - for we have the permanent indwelling Spirit of Christ, Who is a sure witness in our heart that we truly are the children of God.
Loving Father, thank You for the indwelling Holy Spirit and His witness in my heart. I want to abide in You and You in me so that the witness of Your Holy Spirit with my human spirit will have free access to teach to me and to guide me into all truth, in Jesus name I pray, AMEN.
