It is possible to know (1 John 5:13-14), to know and not wish, or "hope so", but to know that you have eternal life! The life comes only through Jesus (1 John 5:11-12). If you have him, you have eternal life. Period.
If that is the case, it will change the way you related to God and to others. You will love God and keep God's commands (1 John 5:3) and you will love the children of God (1 John 5:2). Loving God prevents his commands from being burdensome. If you love God you love to do what he says!
If you have Jesus as your savior, you are born again and have overcome the world. Jesus keeps you from the evil one who rules the world, who seeks your destruction (1 John 5:18) and hates God.
Keep yourselves from idols. An idol is nothing more than a God-substitute. Everyone believes in an idol or in God. So, keep yourselves from idols.
