People are told fantastic things to be lead them to Christ, later to find out that they weren't true; major disappointment. Also, people are lead to Christ and told that God loves them and doesn't expect anything of them; also not true, God does love you and He expects things of you. We are allowed to expect things of God, and God does expect things of His creation, that's why He gave us life. In God's word you will find out what God expects of the true believer and what the true believer can expect of God. In Malachi 3:10 God says to put Him to the test, but that's not the only time that He wants us to test Him. He yearns for the opportunity to prove Himself, but not to brag on Himself.
