God is love. Perfect love drives out fear. My greatest fear I guess, is losing God. But God has dealt with that fear in the gospel. He gives me assurance in the blood of Christ shed for me, that I will never hear those words.
Love is the only possible antidote to our core emotion of fear.
Because only love can convince us that we won't be rejected. Only a great act of love can take away our fear. Jesus, God in the flesh, died in my place. Jesus knew fear like you and I will never know. Yet despite his fear, he accomplished all the Father sent him to do.
