And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance until the redemption of those who are God's possession - to the praise of His glory. Eph. 1:13-14
When we receive the gift of salvation we are placed into Christ and this is eternal agreement between God and us. We become alive in our spirit in which we were once dead. God is able to keep His children and He is able to maintain this relationship with us. We were bought with a price, the precious blood of Jesus Christ. That is the power of our salvation and this doesn't come from us but from God by His Grace and Mercy.
God is able to save, we may choose to turn away and deny Him, but this doesn't keep God from His power and grace to keep our salvation and justification in Christ. God is able to forgive and Christ has all ready died for all our sins that we have, and will commit.
Therefore, be of great hope we can trust and rely on the Great Love that He has for us forever!
