Your line of reasoning is distorted
Grace is not salvation, there was grace before the new covenant in the old testament.
Salvation is the gift imparted to us because of our personal belief in what Jesus has accomplished. The Gift is salvation because we have been declared Justified by the work of Christ Jesus.
Romans 6:23--the gift of God is eternal life
Show me a scripture where God takes the Gift (eternal life) back making it uneternal?
MAKE no mistake......he can lose his salvation, and then has worked to gain it back or keep it......obviously SALVATION cannot be lost nor forfeit....no matter how many scriptures get twisted and or denied....VERB tense, context and the very verbiage of the bible teaches the eternal security found in Christ....
workers for....lose, gain, lose, gin, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gin, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gin, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gin, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gin, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain, lose, gain salvation over and over and over.....
BECAUSE sin causes one to lose it and works must be done or maintained to keep it..............The hope they exercise is like buying a lottery ticket and they HOPE they get the PRIZE at the end......ZERO hope in their message!
