Agnostics I have known are mired in honest doubt and usually say they would believe in God “if I had more proof”.
They lack the angry dogmatism of the determined atheist, you know, the one who mocks believers’ Deity as “skydaddy” or “your imaginary friend”.
The atheist's name for God that I hear and read most often is "Sky Fairy", which I assume is their not so subtle attempt to insult and anger Christians by inferring that the deity who atheists say doesn't exist is "gay", and therefore is just an imaginary "little g" god who practices homosexual acts that are repugnant to believing Christians.
I don't hate or even despise atheists, I have nothing but extreme pity for atheists who maintain that position until death when they kneel before the eternally existent Triune God. In that moment they will learn the truth about the Gospel of Jesus Christ that in natural life they had rejected as nothing more than a farcical fairy tale intended only to pacify gullible, uneducated, and/or simple minded people so that they could be manipulated into serving the wants and needs of the privileged and educated elite.
I don't want anyone to go to Hell for all eternity, the horror of that punishment is impossible to imagine. But there is no other way to avoid that unimaginably horrible punishment other than to accept the salvation that God graciously offers to anyone who repents of (turns from) his/her sins, believes that Jesus Christ is God's divine Son and 2nd person of the Trinity, and accepts Him as Savior and Lord. The term "Lord" means "master" in that transaction, and the one who accepts Jesus as Lord becomes His slave, purchased by the atoning death of God's divine Son Jesus on the cross. A much loved and willing slave to be sure, but a slave none the less.
