Yes the saving work of the Cross
By grace you are saved its the gift of God , Jesus is the reward !!
so many are still bound by the law and are being judged by the Law still but when we try to do good in the Law because we love God and he loves us
the gift of Christ in you the hope of glory comes reward make a gift of something to (someone) in recognition of their services, efforts, or achievements.
Jesus says in the scriptures we search and think life is in them , but its really in the Holy Spirit of Jesus Christ &Father that the Life is given !!!
36 "But I have a ·proof [testimony; witness] about myself that is ·greater [weightier] than that of John. [L For] The ·things [L works] I do, which are the ·things [L works] my Father gave me to ·do [complete; finish; C the signs and miracles which point to his saving work on the cross], ·prove [testify; witness] that the Father sent me.
37 And the Father himself who sent me has given ·proof [testimony; witness] ·about me [concerning me; on my behalf]. You have never heard his voice or seen ·what he looks like [his form; his outward appearance
38 His ·teaching [word; message] does not ·live [remain; abide] in you, because you don't believe in the One the Father sent.
39 You ·carefully study [search; examine] the Scriptures because you think they give you eternal life. They do in fact ·tell [testify; witness] ·about me [concerning me; on my behalf], 40 but you ·refuse [do not want] to come to me to have that life.
41 "I don't ·need [or accept; receive] ·praise [glory; honor] from people.
42 But I know you—I know that you don't have God's love in you.
43 I have come ·from my Father and speak for him [L in my Father's name], ·but [or and] you don't ·accept [receive] me. But when another person comes, ·speaking only for himself [L in his own name], you will ·accept [receive] him.
44 You try to ·get praise [receive glory/honor] from each other, but you do not try to ·get the praise [receive glory/honor] that comes from the only God. So how can you believe?
45 Don't think that I will ·stand before the Father and say you are wrong
[L accuse you before the Father].
The one who ·says you are wrong [L accuses you] is Moses, the one ·you hoped would save you [L in whom you hoped].
46 [L For] If you really believed Moses, you would believe me, because Moses wrote about me [C in the Torah, the first five books of the OT; for example, Deut. 18:15 quoted in Acts 3:22]. 47 But if you don't believe what Moses wrote, how can you believe what I say?"
