Jesus told people to come to him who were tired and depressed. He promised rest. Jesus also promised to remove our sin when we believe that He is the only one who can do it for us. Realizing you are a sinner, and you cannot remove sin yourself is crucial. Asking Jesus to forgive you of your sin and save you is what He says is needed. God's word says that whoever calls on Jesus will be saved (forgiven). This is faith, and you can pray (talk) to him now and ask him; if you are truthful with him, this promise is yours. We are all sinners. We all need forgiveness found only in Jesus.
