You keep him in perfect peace whose mind is stayed on you, because he trusts in you. (Isaiah 26:3)
Jesus answered him, “It is also written: ‘Do not put the Lord your God to the test.’ ” (Matthew 4:7)
Know the difference between trusting God and testing Him.
You can trust God to heal you, but don’t test Him by refusing to visit the doctor He has made available to you.
You can trust God to provide the spouse you pray for, but don’t test Him by waiting for them to come and knock on your door.
You can trust God to provide the finances you need to live, but don’t test Him by sitting at home rather than looking for work.
You can trust God to comfort you when you hurt, but don’t test Him by turning away the friend He has brought into your life to be that comfort.
You can trust God to grow your church and its ministries, but don’t test Him by making promises to your congregation that He hasn’t made to you.
Yes, in Malachi 3:10 God does offer to be tested, but that is in a particular situation regarding tithes.
In all things, examine your heart, as He does, and be sure that you are putting your trust in Him, and not trying to pull His strings.
I’ve known people say that they don’t need anything except Jesus, but their eyes are so firmly fixed on Him that they don’t see the blessings He has surrounded them with. Don’t be one of those people.
