“What man is he who desires life, and loves many days, that he may see good?
Keep your tongue from evil, and thy lips from speaking guile.
Depart from evil, and do good; seek peace, and pursue it.”
This is so simple! If you want eternal life, just do these things: tell the truth and be honest, do good instead of evil, and strive for peace with everyone.
God is not hard. We can do these things, and if we do them, God will guide us into eternal life.
