Is it an attainment? Is it something to do with God? What are the requirements for attaining or achieving Salvation? What did Jesus say about it? Where in the scriptures can we find what Jesus said is necessary for Salvation?
God extends His gift of salvation to all people, but we must go God's way.
1Jn 2:2 And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.
There are no prerequisites to receiving salvation, for we have all sinned.
Rom 3:23-24 for all have sinned and fall short of the glory of God, being justified freely by His grace through the redemption that is in Christ Jesus,
Jesus forgives all of our sin, so that we can come into a relationship with God. However, we must (try as best we can to) live obediently to God as a habit, not making excuses for our old sins.
Gal 5:13 For you, brethren, have been called to liberty; only do not use liberty as an opportunity for the flesh, but through love serve one another.
John 14:15-24 "If you love Me, keep My commandments. And I will pray the Father, and He will give you another Helper, that He may abide with you forever— the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you. I will not leave you orphans; I will come to you. "A little while longer and the world will see Me no more, but you will see Me. Because I live, you will live also. At that day you will know that I am in My Father, and you in Me, and I in you. He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him." Judas (not Iscariot) said to Him, "Lord, how is it that You will manifest Yourself to us, and not to the world?" Jesus answered and said to him, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. He who does not love Me does not keep My words; and the word which you hear is not Mine but the Father's who sent Me.
