The Lord Jesus is always more concerned with what He can do for us, rather than what we can do for Him (Luke 10:40-42). The desire of worship and service to Him and the Father is sought and returned (John 4:23, 24), and if the intention is out of debt (which there is none), the full work and understanding of grace is incomplete where the conscience is concerned, producing an inferior liberation from guilt, which results in the “weighty” reasoning that you will always owe the Father for His grace in Christ. This will spawn a works-based concept by attempting repayment, which never truly satisfies, ending with an inevitable disappointment.
Nowhere is it said in “the word of truth” that the gift of grace, which is “the free gift” (Eph 2:8; Rom 5:15, 16, 18) incurs repayment. Though this gift was at cost, wherein we were “bought with a price,” our desire to “glorify God in your body, and in your spirit, which are God's” (1 Cor 6:20) must find its sole basis in gratitude and love for Them, not out of an owed unpayable debt. This would be a miscomprehension of the proper construct concerning the definition of “gift,”—and “free” at that, not to mention frustration to the overall entailment of God’s love.
I believe one of the primary goals of the Spirit of God is to teach us to focus our faith solely on Scriptural facts within the cannon of the Bible, and minimizing, as much as lies within us from being moved by sense and intemperate emotion. A simple truth to mind is that faith is maintained only through that from which it is formed (Rom 10:17).
