So let's not lose the point of Apologetics. It is to break down some barriers that might be in the way for some to hear or accept the gospel, which is the important thing. The book of Romans is Paul's account of the gospel so I'll quickly go thorough it.
The gospel is the power of God, revealing the righteousness of God through faith. Because God is righteous, He must judge sin. We know we sin because of the Law which God has given us. However, all the Law does is tell us that we have sinned, there is no lasting remedy and there is no assurance of salvation under the Law. This would not be a problem if we were without sin, but we have all fallen short of the glory of God and have therefore sinned. So, we are all to receive judgment because God is righteous.
However, there is a hope given to us. Through Christ we are JUSTIFIED, that means not only are we pardoned, it goes beyond that, there is no case to be brought against us. This is done through His PROPITIATION, which is a once and for all acceptable sacrifice. This leads to us being robed in RIGHTEOUSNESS, which goes beyond being 'ok' with God, we are given the honour of being righteous, like Him. How does this work though? How does believing or having faith in someone else's sacrifice work? Paul discusses this in chapter 4 where he points out that Abraham was acredited with righteousness because of His faith. This was before corcumcision (the covenant) and thus before the law, so salvation has always been through faith. Not just any faith, but faith in God and it is not by works.
This justification leads us to a hope in Christ, a biblical hope is one that does not disappoint and it is different to our everyday sort of hope. This hope is based on God's love for us which is seen through Him giving up His only Son for us, which was not a light sacrifice (see Isiah 53:5). In this hope, we are no longer slaves to sin which produces death, but we are slaves to God which produces abundant life. Being a slave of God is much more free than freedom in sin.
So what do we do with the Law? Do we still follow it? We do still follow the Law because it condemns us wich means it is holy. The Law is good because we know it in our own hearts, each one of us has something that we hold in our hearts and will not tell anyone about it because we know that it is wrong. This is the greater Law which God has placed within our hearts.
Although we have a great hope, God has not promised us that there will be no suffering, in fact, expect it to come thick and fast. However, God does promise that His love will not leave us, no power on earth, in heaven or in hell can seperate us from the love of God. With this hope, we become more than conquerors, in the before, we were subjected to sufferings but now, not only are we not subjected, but we rejoice in them.

So, that's the gospel shortened, but I urge you to read Romans for yourself and see what you make of it!
