Unless you think unbelievers are also elect...
Believing is not the "cause" of our eternal deliverance, but is a product of already having been quickened to a spiritual life.
Eph 2:5 says that we are quickened together with Christ, so, how do you interpret 2 Tim 2:13? "If we believe not, yet he abideth faithful, he cannot deny himself". Unbelievers that have not been quickened, and are not of the elect, will not be quickened.
None of the elect believe until after they have been born again, and even after they have been born again, and are new born babes in Christ, they believe in God, but until they mature through a gradual growth of hearing the gospel, by the revelation of the Holy Ghost, they do not have a knowledge of God's righteousness. This fact is depicted in Rom 10, where paul is praying that Israel ( which is the church, Jacob surname Israel, and not the nation of Israel, because all Israel is not of Israel Rom 9:6) might be saved (delivered from their lack of knowledge) because the men that he was praying for "had a zeal of God" (indicating that they were born again) but not according to knowledge. and were going about trying to establish their own righteousness, by their works, and not submitting themselves unto the righteousness of God.
This is why Jesus instructed his apostles to go and preach to the lost sheep (new born babes in Christ) of the house of Israel (Jacob/Israel, the church) Matt 10:6
Isaiah 28:9-10, Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and are "drawn" from the breasts. For precept must be upon precept, line upon line, here a little, and there a little.
John 6:44, No man can come to me, except the Father which has sent me "draw" him, and I will raise him up at the last day. God does not draw the unregenerate, but those that he has quickened, new born babes in Christ
I believe that Matt 7, about the two gates will harmonize with the fact that those who find the strait gate, are those regenerated children of God who have matured in their knowledge of the righteousness of God that has lead them to that good and abundant life here on earth, whom God has purposed to teach and preach the doctrine of Jesus to those regenerated, new born babes in Christ who go into the wide gate, and are going about trying to establish their own righteousness by their good works, and are not submitting themselves unto the righteousness of God, which leads them to destruction.
Preaching the righteousness of a spiritual God to the unregenerate natural man, depicted in 1 Cor 2:14 would be non productive because he cannot hear to discern, the things of the Spirit, and thinks them to be foolishness. My sheep hear my voice, and I know them, and they follow me, and I give unto them eternal life, and they shall never perish, neither shall any man pluck them out of my hand. John 10:27-28.
