Jesus left behind the perfect gift: the Holy Spirit.
As our Helper, the Holy Spirit teaches us to never have fear in our hearts. It’s truth gives us power to stand steadfast against our enemy.
It’s truth is filled with perfect love, so that our minds can be renewed; therefore we can focus on Him, and Him alone.
Although reality sometimes say something totally different, God is saying, do not fear.
His Holy Spirit is alive, within the believer. Trust it, believe it.
2 Timothy 1:7(NKJV)
For God has not given us a spirit of fear, but of power and of love and of a sound mind.
