Agape love is unconditional as in perfect, principled and not based on anything humans have done to deserve it. John 3:16 God is the only one who has that type of love, and his son.
But love of God means we must keep his commandments. Same for his Son, Jesus.
1 John 5 KJV
1Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
2By this we know that we love the children of God, when we love God, and keep his commandments.
3For this is the love of God, that we keep his commandments: and his commandments are not grievous.
John 14:15 KJV
15If ye love me, keep my commandments.
John 15:14 KJV
14Ye are my friends, if ye do whatsoever I command you.
15Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.
Hebrews 5 KJV
8Though he were a Son, yet learned he obedience by the things which he suffered;
9And being made perfect, he became the author of eternal salvation unto all them that obey him;
So we must obey God, not merely believe in him, in his son and in Jesus' sacrifice, in order to gain salvation.
