Am I not saved if I struggle with habitual sin?

TL;DR:

Struggling with habitual sin doesn’t mean you’re not saved; it often shows a heart that desires Christ and repentance. True salvation is marked by ongoing dependence on Jesus, not by perfection or the absence of struggle.

what does the bible say?

The Bible teaches that Adam and Eve's disobedience brought sin to the human race, and since then, every person has sinned against God in some way (Genesis 3:6; Romans 5:12, 3:23). In the Old Testament, God's people often disobeyed or didn't have the proper heart toward God (Micah 6:8), but He forgave them (Deuteronomy 4:31; Isaiah 49:15). That forgiveness is available to us today (1 John 1:9).

Intentionality is the difference between a Christian who struggles with sin and a professing Christian who leads a life that denies Christ. Paul described his persistant struggle with an unnamed sin (Romans 7:15-25), but the struggle itself shows that he desired to be a servant of Christ rather than a slave to sin. In Romans 8:9 Paul distinguishes between those who “set their minds” on the flesh versus the Spirit (8:5-7).

Lot’s wife is an example of this mindset. As she and her family fled Sodom, she disobeyed God and looked back, implying her heart was still set on the city and its sinful ways (Genesis 19:26). Those who have no desire to grow in Christ and live out the Christian life were never Spirit-indwelt believers (1 John 2:19).

from the old testament

Adam and Eve's sin brought sin to all human beings (Genesis 3:6).
God's people were to be holy, an example to other nations (Leviticus 21:8; Isaiah 42:6), much like God's people today. But despite God's warnings, the Israelites sinned continuously, yet He never abandoned them (Deuteronomy 4:31; Isaiah 49:15).
God promised blessing, grace, and forgiveness for those who lived a life of repentance. (2 Chronicles 7:14; Psalm 32:5; 38:18)
The psalmist wrote, "If I had cherished sin in my heart, the Lord would not have listened" (Psalm 66:18). When we love our sin without repentance, we are not walking with God.

from the new testament

Paul describes his struggle against sin: "For in my inner being I delight in God’s law; but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me" (Romans 7:22-23). The same is true for all Christians, even those who are spiritually mature.
But Paul also identifies what saves us from slavery to sin: "Who will rescue me from this body that is subject to death? Thanks be to God, who delivers me through Jesus Christ our Lord!" (Romans 7:24-25). True repentance for sin is godly sorrow, but worldly sorrow tries to avoid consequences (2 Corinthians 7:10).
The author of Hebrews tells us repeatedly that Jesus' death forgives every sin once and for all time (Hebrews 7:27; 9:12, 26; 10:10)
Struggling with sin is different from abandoning the faith. John indicates that those who abandon the faith were never truly saved: "They went out from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us" (1 John 2:19).

implications for today

The main difference between believers and unbelievers in the struggle with sin is repentance. The Greek word literally means “to change one’s mind.” Repentance is acknowledging that Christ’s way is better than anything we can come up with. It means that—for the addict, especially—we are choosing to put down the bottle, the pipe, or whatever it is that we have been using as a “functional savior” to get us through and we are focusing on Christ. It means recognizing our sin and doing what we need to do pursue God, not our sin.

The Holy Spirit is the One who transforms us and grows us into Christlikeness, but it requires our surrender. Spiritual disciplines can help us in this formation. For example, communing with our heavenly Father in prayer and regularly reading His Word as well as associating with other believers can help us shift the focus away from immediate gratification and onto Christ where it belongs. Every step of repentance, every moment we turn from self to Christ, is proof that His grace is at work in us, shaping us into who He created us to be.

understand

All believers struggle with sin; the difference is in repentance.
Struggling with sin means that in your heart you really want to stop; heed that voice.
Habitual sin can be a sign that we are not saved, but it can also be a sign of where we are in our faith journey; what is important is our surrender and repentance.
