Getting your footing on the grounds of grace is scary. It hurts so much to come to the realization that I am not in control and I can not trust myself.
I don't know if Jesus was referring to the road of faith when he descirbed the narrow way that leads to life as being difficult.
I'm not allowed to control my behavior with condemnation. How can I when I am confronted with the fact that I am loved unconditionally? I am no longer under the law and therefore am no longer condemned. Understand that when I say I can't be condemned, I mean that a lot of times I would like to go back to law, but I can't. I just can't be afraid of God anymore. I know who He is.
Jonah KNEW who God was. He KNEW God's ways and that God was abounding in lovingkindness. That is why he didn't preach to the Gentiles. He knew God would love the people that Jondah thought were absolutely unlovable. He didn't want Him to love them. Jonah was not afraid of God...He ran from Him and talked back to Him: "Yes I do well to be angry! Angry enough to die!"
Even Cain, after he killed his brother, knew of God's lovingkindness and how it endures forever. After Cain killed his brother, Abel, God asks him what he's done, and he back sasses God with a smart attitude: "How should I know? Am I my brother's babysitter?" And how does God respond? By putting a seal on the murderer, protecting him!
I'm not saying Cain was saved since the Bible doesn't ever hint at him being saved. He tried to offer God fruit rather than the blood of a Lamb. I'm not saying he was saved, but I am saying God clearly demonstrated His true character of Agape by putting a seal of protection on someone who just murdered their own brother.
We have not received a spirit of slavery to fall back into fear. We have received the Spirit of adoption as sons. You are not a slave, but a son. You are not God's employee, you are His son. If God protected Cain, a faithless murderer, will He not much more protect you from the wrath to come?
