Romans 8:15 says, "You did not receive the spirit of bondage leading to fear, but you received the Spirit of adoption, by whom we cry, "Abba! Father!"
What are most Christians afraid of?
That God is not pleased with them. That they will lose favor with God. That they have offended God. That God will break fellowship with them. That God is cursing them because of something they've done. That sin separates them from God. That God won't protect them. That God won't provide for them. That they aren't doing enough, aren't praying enough, aren't witnessing enough, aren't reading the bible enough. That God doesn't love them very much if at all.
Every one of those fears is a lie. Jesus didn't commit the ultimate act of love for you to sit and wonder, "How can God really love me after all I've done and keep on doing?" He loves you more than you'll ever know because "his love surpasses all knowledge" (Ephesians 3:19).
Cry out, "Abba! Father! Jesus! .. Deliver me from believing these lies that make me think 'yeah, you'd die for me but you wouldn't live for me.' Jesus I never again want to feel like your death wasn't good enough so I have to add to it. I don't ever again want to think that your love for me is conditional or that your pleasure in me comes only from my performance. God I want to recognize your love for me every moment I possibly can. May I always know that the gospel is the good news of your graciousness not the bad news of all I have to struggle to give back. I'm tired of trying to earn what I already have and reaching for what is not mine. I want to live in what you give, who you gave. I want your promises to reshape my perceptions. Jesus after you finished offering yourself as the sacrifice for sins you sat down at the right hand of the Father. My life is now hidden with Jesus in you Father because you raised me up with Jesus and sat me with Him. The work is done, it is finished, paid in full! I want to rest with you. You said 'come to me and I will give you rest.' Here I am Lord. Here I am Father. Here I am friend."
How do you rest with someone? You trust them, you feel secure with them, and you relax!
