How do we know what is good? The Bible tells us that God is good. In fact, it speaks of His goodness throughout Scripture.
“The Lord is good to those who wait for Him, to the soul who seeks Him. It is good that one should hope and wait quietly for the salvation of the Lord.” Lamentations 3:25-26.
During the Sermon on the Mount the Lord Jesus gave us a model for prayer, it goes as follows.
“In this manner, therefore, pray: Our Father in heaven, Hallowed be Your name. Your kingdom come. Your will be done on earth as it is in heaven. Give us this day our daily bread. And forgive us our debts, as we forgive our debtors. And do not lead us into temptation, but deliver us from the evil one. For Yours is the kingdom and the power and the glory forever. Amen. For if you forgive men their trespasses, your heavenly Father will also forgive you. But if you do not forgive men their trespasses, neither will your Father forgive your trespasses.” Matthew 6:9-15.
“Then a leper came to Him, imploring Him, kneeling down to Him and saying to Him, ‘If You are willing, You can make me clean.’ Then Jesus, moved with compassion, put out His hand and touched him, and said to him, ‘I am willing; be cleansed.’ And as soon as He had spoken, immediately the leprosy left him, and he was cleansed.” Mark 1:40-42.
