You are accepted, you can trust this to be true. Acceptance by God has nothing to do with what you do, but who He is in you. You are a child of God by virtue of God joining His Spirit with your soul. His Spirit, resident within you, lets you boldly say you are both His child and accepted. You know the difference between trusting God and not trusting God. If you do not have the witness within, then you distrust Him.
"(The one who trusts the Son of God has the 'know so' in himself. The one who does not trust what God has said has just called God a liar, because that one has decided not to trust the testimony that God has testified concerning his Son.)" 1 John 5:10 (DLT)
"And this is the testimony: God has given you eternal life. This life is his Son. You, who have the Son, are alive; not trusting the Son of God is death." 1 John 5:12(DLT)
So when are you accepted? When you accept the Son. It is like trusting what God declares is true right now, personally. Doubting it is true is calling God a liar, or believing the lie that says, "you're not accepted".
