You can end up sealed and a Child of GOD some day ...but right now ...no. A Child of GOD doesn't have repeated willful sin in their life. They are Righteous. To be clear ...you can't be Righteous with repeated willful sin ...hello? Is this not obvious?
1 John 3:4-10 ESV
4 Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness.
5 You know that he appeared in order to take away sins, and in him there is no sin.
6 No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him.
7 Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous.
8 Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil.
9 No one born of God makes a practice of sinning, for God's seed abides in him; and he cannot keep on sinning, because he has been born of God.
10 By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.
// You just read the reason for The Son of GOD to be here was to destroy the works of the devil ...and yet, you continue to do them.
