The "gospel" or "good news" that Paul speaks about in his epistles centers around being "in Christ", because in "Adam" we all die. (1 Corinthians 15:22). "In Adam", our relationship with God was broken, we were disconnected from the source of love and life. We have a longing in our heart that only God can satisfy and all of us at some point have tried to satisfy it with something or someone else (Ecclesiastes 3:11, Jeremiah 2:13).
The "good news" of the gospel is that "in Christ", you are brought back to God and you become a new creation. (see 2 Corinthians 5:17-19). Jesus identified himself with all the bad, whether done by you or done to you and nailed it all to the cross. In return, you become identified by His good life, His thoughts, feelings and attitude. (2 Corinthians 5:21). We experience the new life by thanking God for what Jesus did and continues to do in us. (Philippians 1:6). When we really appreciate His love and value for us, it will only be natural to worship Him in the beauty of holiness.
We completely miss the point of the gospel when we inspect fruits (behaviors) of sin, but never address the tree and root, which is the separation from God. Whatever your temptations may be, the good news is that it's not up to you to overcome temptation in your own strength, but when you come into a close relationship with Jesus, He overcomes it for you. (1 Corinthians 15:57).
How we treat others different than us is a reflection of our picture of God, we all truly live out our theology (1 John 4:8). That's why it's so important for us to really get to really get to know Jesus personally and His good news (the gospel) for you and everyone around you. We need to know the value we have in God's eyes and that's what the gospel will show us. When we really take the time to know the good news about God's love for us and His power to change our hearts, we will want to share that with others.
