I was just reading about Jesus’ teaching that if you forg8ve, you will be forgiven; nut if you do not forgive, you will not be forgiven. He repeated that several times; he seems quite definite on that point.
So, can salvation and grace be lost? I conclude that if you forgive, you will be forgiven. If not, not.
John 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
*Has passed* = past tense. It's not *will pass* as in a future date.
John 6:37-39 All that the Father gives me will come to me, and whoever comes to me I will never cast out. For I have come down from heaven, not to do my own will but the will of him who sent me. And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.
John 10:25-30 Jesus answered them, I told you, and you do not believe. The works that I do in my Father's name bear witness about me, but you do not believe because you are not among my sheep. My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand. I and the Father are one.
