The answer is Wrong.
Jesus came to save sinners like us and not to condemn us. He wouldnt ask us to do something that were impossible. Rather he said that if we believed, even the impossible would be possible. The Mosaic law was given to Israel by a man called Moses. Israel were expected to fall. But Jesus is the Mighty God that Isaiah prophesied about. Is 9:6. What Moses said was difficult to keep but what Jesus requires of us, though humanly impossible, is possible if we lean on the power of God. It is possible because he gives us the Spirit of the Living God to help us. He dwells in us. The spirit that lives in us is the same spirit that raised Jesus from the dead. Rom 8:11. Which means we have the resurrection power of Christ dwelling in us. Dwell on that word. Just like God raised Jesus from the dead by defeating death, we can defeat any dead work in our life and be victorious overcomers in Jesus name.
To illustrate, lets assume someone who has wronged you has received the just reward for his evil deeds 'cause now he is in a gutter for what he did. When you pass by that gutter, that person apologises for the wrong he did to you. You can say,"Alright I forgive you." and walk away. Then you would have forgiven him but he would still be in the gutter wondering why he is still there if he has been forgiven. The other way would be to say,"I forgive you", and then get into the gutter to help him get out. Then you would have forgiven him and saved him. Jesus came not just to forgive our sins but to save us from them. Just like a man saved from the gutter doesnt live in the gutter anymore, a man saved from SIN will not live in SIN anymore. So if we are still sinning; we can be assured of the fact that we are not SAVED and are still in the gutter of SIN.
It is hence very important to fellowship with Godly brothers and sisters from your church. Church, The body of christ is the safest place to be on earth because Jesus said that whenever the Church (even a church of 2 or 3) gathers in his name, he will be there. Thats a promise, and Jesus is faithful to keep it. The church enables us to receive and to provide encouragement, rebuke, love, correction to each other. The Church is a representation of the body of Christ and the command given to it is to press on unto perfection. Heb 6:1. May be we are not perfect, but we will be one day, if we continue to run the race looking unto Jesus. He is the author and perfector of our faith. Heb 12:2. If we depend on him, WE WILL NEVER FALL.
