It’s a frightening and tense place to be in when you are uncertain about where you stand in your relationship with Jesus Christ. Understanding the basis and the nature of salvation can eliminate much of the uncertainty that some Christians feel regarding their relationship with Jesus Christ.

The Bible stresses that salvation completely rests on trusting in Jesus Christ’s death on the cross as full payment for our sins ( John 3:15-16,36 ; Romans 3:22-24 ). Faith alone is the basis for our salvation. It is not based on our own merit or performance ( Ephesians 2:8-9 ; Titus 3:4-5 ), nor is it based on the amount of our faith. It is the object of our faith that matters. Trusting in Christ (not anyone else, including ourselves) brings salvation. A strong sense of security settles in our hearts as we realize that while we are the fortunate recipient of God’s grace and mercy, we are not responsible for earning it. It’s free!

Additionally, the Bible teaches that we are eternally secure when we solely trust the Lord Jesus Christ as our Savior. This is the eternal and binding nature of the salvation that Jesus grants. Jesus said that He gives us eternal life and we shall never be lost. He declared that no one can take us out of His or the Father’s hands ( John 10:27-30 ).

In the same way, the apostle Paul wrote that those who have trusted in Christ for salvation are eternally saved. He stated, “There is now no condemnation for those who are in Christ Jesus” ( Romans 8:1 ). He went on to say that absolutely nothing can separate us from God’s love ( Romans 8:35-39 ). So then, according to the Scriptures, we can confidently believe that we are eternally secure if we have placed our trust solely in what Christ accomplished on the cross as full payment for our sins ( John 5:24 ; 1 John 5:13 ).

If we could somehow lose our salvation in Christ, then Jesus and Paul would be liars since they both described the gift of salvation as eternal ( John 3:16 ; Titus 3:7 ). Eternal means that it never ends. Our salvation is permanent. In other words, once we are saved, we are always saved.

God doesn’t give us the gift of eternal life and then take it back if we are bad. Our eternal security is not based on our ability to be good or perform, but on the promises of God ( John 3:16 ). Moreover, any attempt on our part to say that we can somehow earn and maintain a secure relationship in Christ is an affront to God. It strips Him of glory and lessens His remarkable offering of grace and mercy to an undeserving world.

Although we never lose our salvation in Christ, we can lose the enjoyment of close communion and fellowship with our heavenly Father. For example, when my daughter sins against me, it temporarily hinders our ability to be close and enjoy each other’s company. But even though all is not well between us, she never ceases to be my daughter. The same is true for those of us who have trusted Christ as our Savior. Whenever we sin against God and put distance between ourselves and Him, we are still His children who are secure in His love. That is why in Luke 7 Jesus told the sinful woman whose faith had saved her to “go in peace” ( Luke 7:50 ). She could rest and not worry about where she stood with God. That relationship was eternally secure.

We will sin as Christians, and our sin should grieve us. But it shouldn’t take us by surprise. The apostle John said, “If we claim to be without sin, we deceive ourselves and the truth is not in us” ( 1 John 1:8 ). Most importantly, there is no sin we could commit that would cause us to lose our salvation. The apostle John added that God is willing to forgive all of our sins if we confess them ( 1 John 1:9 ). He didn’t just mean the total amount of our sins, but the various kinds of sins as well. In other words, God forgives and cleanses us from every kind of sin possible. His mercy has no limits.
