基督教 christianity

Actually, your question coversthe teaching of the whole bible. Below I selectively pick out some verse as my answer.
God has revealed through the Bible how should His people live in order to please Him. The most important one is TRUST AND OBEY God.
You can find the 10 commandments in the book of Exodus chapter 20, which can be summed up as:
Love the LORD your God with all your heart and with all your soul and with all your strength. (Deut 6:5) and Love your neighbour as yourself. (Lev 19:18).
God has repeatedly reminded His people through prophets how to live. For example, Micah 6:8
O man, what is good.
And what does the LORD require of you?
To act justly and to love mercy
and to walk humbly with your God.
For example, through James, God urges His people has to be completed.
Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world. (James 1:27)
Through John:
7Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. 8Whoever does not love does not know God, because God is love. (1 John 4:7-8)
Now all has been heard;
here is the conclusion of the matter:
Fear God and keep his commandments,
for this is the whole duty of man. (Ecc 12:13)
