You have no other "assurance" than your interpretation of Scripture.
No, I have the assurance in Christ.
You have no other "assurance" than your interpretation of Scripture.
Yet we read in Romans 8:
"15 For you did not receive a spirit that makes you a slave again to fear, but you received the Spirit of sonship. And by him we cry, "Abba, Father." 16 The Spirit himself testifies with our spirit that we are God's children."
From the 1689 Baptist Confession of Faith:
18.2 This certainty is not mere conjecture or probability based on a fallible hope. Rather it is an infallible assurance of faith based on the blood and righteousness of Christ revealed in the Gospel, on the inward evidence of those graces of the Spirit (about which promises have been made), and on the testimony of the Spirit of adoption who witnesses with our spirits that we are the children of God. As the fruit of this assurance, the Spirit keeps our hearts both humble and holy.
18.3 This infallible assurance is not an essential part of faith, for a true believer may wait a long time, and struggle with many difficulties before obtaining it. Yet we may obtain it without extraordinary revelation and by the right use of ordinary means, for we are enabled by the Spirit to know the things which are freely given to us by God. Therefore it is the duty of everyone to be as diligent as possible to make their calling and election sure, so that their hearts may be enlarged in peace and joy in the Holy Spirit, in love and thankfulness to God, and in strength and cheerfulness in carrying out the duties of obedience. These duties are the natural fruits of this assurance, for it is far from inclining people to loose living.
My experience follows the confession - that assurance didn't come immediately, but followed as I matured and came to know more of God & Scripture.
If you lack assurance, I suggest you carefully consider your beliefs. For in scripture, our justification is past tense. There is no basis in scripture for facing death without assurance of eternal life, unless such is your choice.
