>> Without justification we are lost - and we cannot achieve (nor add too) justification. <<
That is true, but justification alone is not enough. Living an abundant, holy life requires obeying the will of God; impossible without being filled (controlled) by the Spirit of God (Eph. 5:15-18).
Please - do not try to “add” to the completed work of Jesus on the cross. He “Justified” us before the Father. If we need to add anything to that, then He failed. Indeed, we CANNOT add anything to the completed work of Jesus.
Everyone since Paul has struggled with this: “It really cannot be that simple!”
But it is - the Father has longed to “walk in the cool of the evening with His man”, and now Jesus has made this possible.
Once we realized - appreciate - accepted that we are truly Justified, then everything else - everything else - falls into place.
Neither the Father nor the Son can see our sin - the Holy Spirit resides in us to convict us of sin and to keep us in His Grace.
The hard part is not making this too hard - the work has been completed - and we stand fully Justified before our Creator - Hallelujah!!
