Howdy. Welcome to the forum.
It seems to me that the prospect of Hell could be be a powerful motivator, but also a major source of anxiety.
Hell is a real place and there really will be people sentenced to Hell. But the keys to Hell belong to Christ alone and He is more merciful with us than we are with our own children. So it seems to me that it should
be a motivator, to an extent, but at the same time we don't want our faith in Him to be some sort of spiritual fire insurance. A very beloved saint in the Eastern Orthodox Church, St. Silouan, has said, "Keep your mind on hell and despair not." In other words, hell is real and Christ revealed to St. Silouan that he (and all of us) are to remember that. But then he goes further and says, "...And despair not." How can we focus on Hell and not despair? Christ meant that we are to lean on Him, be focused on Him and not ourselves, for the Holy Spirit, the Paraclete, is with us to comfort us.
Does the prospect of Hell have an effect on you like this?
It motivates me to be more watchful and to pray more. But I don't believe it's healthy to simply focus on Hell. God doesn't want us to love and follow Him out of fear, but out of love.
Hope this helped a little.
