Does believing play a part in Salvation ? 3
Yes Believing plays a Huge part in Salvation in that we believe because we are saved, there is no believing unless we are saved first, for we cannot believe in a lost state ! The Gospel is hid to them that are in a lost state so that they cannot believe being blinded by the devil, or the god/prince of this world 2 Cor 4:3-4 ! Hence we believe because of being saved by and through Grace Acts 18:27
27 And when he was disposed to pass into Achaia, the brethren wrote, exhorting the disciples to receive him: who, when he was come,
helped them much which had believed through grace:
They believed because of being saved by Grace. The word through here is the preposition dia, which means :
on account of, by reason of, for the sake of, or because of Grace ! Not because of freewill as the proud boaster would have us believe, but again because of Grace, the Grace of the Spirit Zech 12:10.
Grace here is said to be the author and efficient cause of their believing, because of Grace which is the Gift of God !
The word grace in Acts 18:27 is charis and means:
A.of the merciful kindness by which God, exerting his holy influence upon souls, turns them to Christ, keeps, strengthens, increases them in Christian faith, knowledge, affection, and kindles them to the exercise of the Christian virtues
Its the Gift by Grace Rom 5:15
But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God,
and the gift by grace, which is by one man, Jesus Christ,
hath abounded unto many.
This Grace abounds victoriously towards us through the Lord Jesus Christ, and is similar to the fact that with the giving of His Son for us, with Him He gave us all things that produces and pertains to Life and godliness Rom 8:32 ; 2 Pet 1:3 ! And Godliness is to Acknowledge the Truth Titus 1:1
Paul, a servant of God, and an apostle of Jesus Christ, according to the faith of God's elect,
and the acknowledging of the truth which is after godliness;
And thats what results us believing, because of Grace through Jesus Christ Jn 1:16-17 !
