I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life. 1 John 5:13 (NLT)
What makes the Gospel such Good News is the assurance it gives us! We don’t have to live with a hope so, maybe so faith! We can live with a confident know so kind of faith! If you’re married, there may be times you may not feel married, but you most likely have never doubted being married. You entered into a relationship that was intimate and personal! There were witnesses present at your wedding. It was a legal and binding covenant between you and your spouse.
When you open your heart to Christ, He comes in to take up residence in your life. He is the eternal life you received and, when you receive Christ, you receive His life. God wants you to know that you have eternal life. That word for “know” in the Greek refers to an experiential, relational knowledge that removes all doubt and secures your acceptance before God as His forever child. You didn’t deserve it and you could never earn it. You couldn’t purchase it if you had all the money in the world. His life is offered freely to us. Grace is free, but it isn’t cheap. It cost Him His life on the cross to provide the assurance of eternal life for you and me.
If you’ve ever doubted your salvation or wondered if you could really know that you have eternal life, this verse is for you. God wants you to live with the confidence of knowing that your sins are forgiven and you have a home in heaven. He wants you to know that you have eternal life now, not just when you die someday. Knowing that now makes all the difference in living with confidence and assurance or living with doubt and fear. The very next verse underscores that by saying, “This is the confidence we have in approaching God….”
You can have that same confidence too! Like a child of a loving and compassionate father, you can enter boldly into His presence and call Him Abba Father. Abba is the Aramaic term of endearment that means Papa or Daddy. When a child is loved like that, he is secure and confident.
So you have not received a spirit that makes you fearful slaves. Instead, you received God’s Spirit when He adopted you as His own children. Now we call Him, “Abba, Father.” For His Spirit joins with our spirit to affirm that we are God’s children. Romans 8:15-16 (NLT)
