Yes there's redemption; that's ultimately what salvation is all about. Just as your soul can get sick, it can also be healed, but only God has that power. Basically, if you love Jesus Christ, then his love will save you, but if you hate or reject him, then his love will burn you. So loving God is the basic act through which you heal your soul so that it is in alignment with him. But, unlike in Protestantism, the love of Christ isn't simply an extrinsic symbolic act that you just do and then you've got a permanent ticket into heaven. In Orthodoxy, salvation is intrinsic, and continuous. This means you have to genuinely love him, and you have to cultivate that love throughout your life. If you don't love God, then you're closing your heart to his love, and therefore his love can no longer heal your soul to ensure that you make it into his Kingdom.
It's sort of like if there was a magic Fountain of Youth buried under the sand in the desert. As long as you are drinking from the fountain regularly, you'll have eternal life. But to get to it, you have to put in the work to actually dig the sand away to drink from the fountain. But if you stop working, the sand will fill up the hole again, cutting you off from your own salvation. So to maintain that steady drink, you have to maintain a steady life of work.
This work to love god involves not only loving him, but also loving yourself (since he created you), and your fellow man, and all of his creation. When it comes to loving your fellow man, keep in mind this "love" isn't like the hippy cuck type of love, but rather a much deeper sort of spiritual respect. When you love thy enemy, for example, that doesn't mean you don't kick his ass or even kill him when you need to, it just means that you're not going to use that as an excuse to torture him for hell of it, or go rape his wife just because you can, and it also means that if he seems to genuinely want to stop being your enemy, then you should (cautiously) give him a chance to redeem himself. So it's about having a deep respect for God's creation, in addition to loving God as you would love a (good) father. And, since God created you, that means you must also love yourself. This doesn't mean narcissism, but rather self-respect. That means staying fit, healthy, and clean, and keeping your mind free of self-hating thoughts.
As for loving God, that's something that has to be cultivated personally, but the basic starting point is to follow his commandments, which means avoid sin. And if you do commit sin, genuinely ask him for forgiveness while making a genuine effort to proactively avoid repeating it in the future. Note that the Greek origin of the word "repent" means "to turn around 180 degrees"; so it means an actual change of direction, not just saying "lol im sorry" and then doing it again. The primary method of cultivating the love of God and thus allowing his love to save you is through prayer. This doesn't mean asking him for a new car or to smite your enemies. It means asking him for forgiveness (the basic prayer is called the Jesus Prayer: "Lord Jesus Christ, have mercy on me"). Again, it's all intrinsic, so it's a matter of what's really in your heart, not some silly external gesture like some heathens have convinced themselves of because it makes it sound so much easier. In addition to prayer, there are various ascetic practices like fasting (which can be not only regarding food, but also any other indulgence). For the average Christian, these should be practiced with the goal of achieving a balance in life, so as to avoid over-indulgence and addiction. But it's all optional, and usually only people who choose to become monks will practice these to any extreme degree, like vows of silence, vows of celibacy, living in a cave off in a forest or desert for 40 years, etc. These people choose to do these things because they feel that for them, this is necessary. Each person's soul is unique and therefore there is no single formula for everyone, it's rather something that you have to figure out between you and God, with the (optional, but useful) guidance of your priest.
Ultimately, healing your soul is what the Orthodox Church is all about. In fact they see the church itself as a spiritual hospital, and the priest as a spiritual doctor. This healing process is a continuous process throughout our lives, because our imperfect nature (due to Satan's sabotage at the Garden of Eden) causes us to sin all the time (even if they're just "small" sins like failing to do good when you had the opportunity to do so), and especially since we're surrounded by degeneracy and temptation to draw us away from a connection with God.
Anyway I could write a book on it, but hopefully that answers your question. I'd recommend googling or searching youtube for more info if you're interested, but going to a service and talking to a priest would be best.
