true conversion

i'm having a hard time. every day i go back and forth sometimes a dozen times between confidently looking to Jesus' righteousness for my hope on the one hand, and feeling like i must be lost due to my own daily sin and lack of evidence of conversion on the other. it has me wondering if i'm truly converted.

before conversion i had thoughts of, "you aren't good enough, look at your sin!" and by God's grace was shown that my sin is very serious but that Christ's redemption is sufficient to cover them all.

now that I have been converted (i hope), the thoughts come, "you aren't good enough, where is the evidence of your power over sin?!"

grace taught me to disregard the accusing 'voice' that said my sin was too great to be forgiven by Christ's sacrifice.

but what am i to do with these post-conversion thoughts? could it be that this post-conversion 'voice' is the Holy Spirit telling me that i haven't truly been converted?

where i get really fearful and confused is verses like the following which say who will and will not inherit the Kingdom of God, "For this you know,[a] that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God. 6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. 7 Therefore do not be partakers with them." Ephesians 5: 5-7

if I'm honest with my heart, there is covetousness in there and i'm sure forms of idolatry. i see a laziness in my bones.

and Jesus said, "why do you call Me Lord and not do what I say?" if i needed Him to cover my past sins by His blood, how can I suddenly obey Him perfectly?

if doing what He says means obeying Him perfectly, who can do that? who can truly call Him Lord?

i thank anyone who can venture to give me some true biblical guidance in this matter.
thanks,
