Psalm 15 says:
Lord, who may enter your Temple?
Who may worship on Zion, your sacred hill?
A person who obeys God in everything and always does what is right,
whose words are true and sincere, and who does not slander others.
He does no wrong to his friends nor spreads rumors about his neighbors.
He despises those whom God rejects, but honors those who obey the Lord.
He always does what he promise, no matter how much it may cost.
He makes loans without charging interest and cannot be bribed to testify against the innocent.
Whoever does these things will always be secure. (Good News Bible with Deuterocanonicals/Apocrypha, 1979, New York, NY: American Bible Society).
This Psalm provides a simple, but well-rounded version of how a person should live. By giving the instructions on how to live, along with the rewards for doing so, it is easy to see how living in this way would be worthwhile. Some behaviors are not always easy to change; but, it is possible.
One possibility would be to take the approach of working on one piece at a time. To enter into the Temple would require an attitude change, one of allowing a higher power have an influence in how each day is considered.
The second part refers to doing what is right. This can include any number of possibilities, but it generally involves kindness, generosity, care, and concern for others.
Next is about the words that are used in conversation. Spreading rumors, telling lies, and creating drama is not in God’s plan. Negativity brings people down. Words should be used to uplift others and bring positivity to light.
The next line is about relationships. The people that make up a person’s life makes a difference in the influence that is brought about. Hanging around with the wrong people is not what God wants. Wrong relationships need to be broken and let go of. It may not be easy, but it is extremely important. Life goes on.
God does what He promises. Through prayer, God becomes a great partner in a relationship that is like no other. He strengthens those who believe in Him.
Money is a gift from God. As such, it is to be shared with those in need; not hoarded. When loaned out, it should be given without any recourse. Any expectation of interest being paid or being paid back can create grudges, hard feelings, and ruin relationships. This is not what God wants.
God holds those who believe in the palm of His hand. He guides and protects those who live in the way He directs.
