Hi Abigail,
I think it really depends on what you're referring to. Jesus said that he sends the rain and sunshine even on unbelievers so there's no condition for some blessings.
I would have to say that everything is conditioned. Here are a few examples below.
Ephesians 6:2 - Condition is honor parents
Children, obey your parents in the Lord, for this is right. Honor your father and mother (which is the first commandment with a promise), so that it may be well with you, and that you may live long on the earth.
Philippians 4:6, 7 - Condition is don't worry
Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus.
James 4:3 - Condition is pure motives
You ask and do not receive, because you ask with wrong motives, so that you may spend it on your pleasures.
Matthew 6:17, 18 - Conditioned upon secrecy
But you, when you fast, anoint your head and wash your face so that your fasting will not be noticed by men, but by your Father who is in secret; and your Father who sees what is done in secret will reward you.
Matthew 6:33 - Conditioned upon seeking first His kingdom and His righteousness
But seek first His kingdom and His righteousness, and all these things will be added to you.
James 1:25 - Conditioned on obedience
But one who looks intently at the perfect law, the law of liberty, and abides by it, not having become a forgetful hearer but an effectual doer, this man will be blessed in what he does.
Jesus also said if you want to be called His friend that you must obey Him. Most everything is conditioned on love, faith and obedience.
John 15:10, 11
If you keep My commandments, you will abide in My love; just as I have kept My Father’s commandments and abide in His love. These things I have spoken to you so that My joy may be in you, and that your joy may be made full.
