Jesus accepts us where we are, as long as we come to Him with a sincere heart. Otherwise no one would have a chance. The difference between grace and law is that grace covers our imperfections, while law condemns.
For sin will have no dominion over you, since you are not under law but under grace. -Rom 6:14
For Christ is the end of the law for righteousness to everyone who believes. -Rom 10:4
Even while we're still struggling with sin, God is not imputing it to us, He is on our side helping us.
in Christ, God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. -2Cor 5:19
Even if you're not perfect yet, if you forgive in obedience you are honoring Christ and His word. That's an excellent start. Do that, and keep working on loving your enemies and forgiving from the heart. Work with what you have, and more will be given.
Because we are under grace, not law, we have the freedom not to be perfect yet, and we have the freedom to grow. It's like teaching a kid to bake a cake. They make a mess, they make mistakes, but that's how they learn. Soon they get it. If they are yelled at every time, at some point they'll give up and never learn.
Give Romans 8 and 2 Corinthians 3 a read if you will. The grace of God is a powerful thing, and can do far more than the law ever could. We have an amazing covenant based on the love of God in Christ Jesus.
