Therefore he is able, once and forever, to save those who come to God through him. He lives forever to intercede with God on their behalf. Hebrews 7:25
Loving it, leaving it or losing it.
Let's take this passage as it was intended. It seems to be a stanza that Paul is reminding Timothy of. I believe we can discover the truth if we break it down verse by verse.
Eternal securityIf we believe not, yet he abideth faithful: he cannot deny himself.
Can you see the progression in this stanza? Our eternal life begins at salvation, our eternal rewards throughout our Christian life and the assurance and security of this great salvation.
Now how does this portion even remotely agree with the idea that you can give your salvation back? It obviously doesn't. In context then how can we then interpret these three verses as referencing one who has walked away from their salvation?
Even if one could "give it back"who says He would accept it? If we believe not He is faithful. He cannot deny Himself. Why does Paul use this phrase? Because once we accept the free gift of grace and receive the Lord we are adopted and the Lord lives within us in the person of the Holy Spirit. So how can God tell Himself I quit you? How can the new creation heart, with the agape love of God shed abroad within it, where the Spirit of God abides "harden" to the point of quitting and returning the gift of eternal life? It is an impossible equation. This verse proves this! Even if you say you quit He remains faithful. He is forever faithful.
This is proven truth because the very faith we have to believe in Him and accept His free gift is His faith to begin with. Faith comes by hearing His Word. His Word like seed is planted in our hearts and harvests faith that we then respond with and receive the Lord Jesus in our life and heart. Again, how can His faith deny Him the author of our faith? How can the Author and Finisher of our faith lead us to a place where we reject Him? He authored our faith and He will finish it to completion presenting us faultless before the throne.
The more we simply study the Word of God it becomes abundantly clear this salvation is completely secure in Him. We can't leave it or lose it. He is forever faithful. I trust this lesson has blessed you. May His grace grow big in you!
