According to the Apostle John, the love of God is in keeping His commandments:
1 John 5:1–3 Whoever believes that Jesus is the Christ is born of God, and whoever loves the Father loves the child born of Him. By this we know that we love the children of God, when we love God and observe His commandments. For this is the love of God, that we keep His commandments; and His commandments are not burdensome.
Jude warned against those who “turn the grace of our God into licentiousness and deny our only Master and Lord, Jesus Christ.” (Jude 1:4) The danger you’re putting yourself in is not that you may become the least in the Kingdom of God, it is that you will not make it to Heaven at all.
