I changed when my image of God changed. I had placed my faith in Jesus, the Son of God, yet I needed to change my image of God the Father - an image of a vengeful, wrathful, mad Father who pours His wrath out on all who do not accept His Son Jesus as their Savior. That image kept me in fear.
“God is love…perfect love drives out fear." (1 John 4:8, 18)
The Bible tell me how God's love acts toward me and all others...
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, and it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres. Love never fails….” (1 Corinthians 13:5-8)
Therefore, like our Apostle Paul, my image of God changed, and now...
"I am persuaded that neither death nor life, nor messengers, nor sovereignties, nor the present, nor what is impending, nor powers, nor height, nor depth, nor any other creation, will be able to separate us from the love of God in Christ Jesus, our Lord." (Romans 8:38-39)
When my image of God became one of love - fear was gone! I knew that a just God saves those He loves, whatever the cost to Him.
"God is commending this love of His to us, seeing that, while we are still sinners, Christ died for our sakes. Much rather, then, being now justified in His blood, we shall be saved from indignation, through Him. For if, being enemies, we were conciliated to God through the death of His Son, much rather, being conciliated, we shall be saved in His life." (Romans 5:8-10)
