"Come now, let us reason together, says the LORD: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool. If you are willing and obedient, you shall eat the good of the land; but if you refuse and rebel, you shall be eaten by the sword; for the mouth of the LORD has spoken." "(Isa 1:18-20 ESV)
The Bible in Isaiah 1:18 says that we can. In fact, this passage says that if we want to be clean of our sin, then we must. Also, this reasoning ability that we have is not an infringement on God's sovereignty as some mighy think. Nor, on the other hand, does God's sovereignty infringe on our own will to behave wisely and act responsibly. I deal with this whole discussion of God's sovereignty and man's free will in Defense "Why we Believe" 5 and 6 The Providence of God Parts 1 and 2.
It is clear from a number of Scripture texts that God is absolutely sovereign in all affairs (cf. Proverbs 16:33; Matthew 10:29; Ephesians 1:11, to name a few). Nothing is a mystery to God and nothing happens without His knowledge. However, the overemphasis on God's sovereignty, also known as Calvinism, if taken to the extreme, results in no free will or determinism. Determinism, is also the end product of atheism because on atheism there is no real meaning to our lives-- everything just happens and there is no accountability or reason.
There are also many scriptures like Isaiah 1:18 that tell us we can make choices and are responsible for those choices (cf. Joshua 24:15 and John 3:16 are also just two among others). An over-focus on free will, or Arminianism, if left unfettred, can lead to a belief that God really does not know the future and is helpless to affect it. This is known as the false teaching of Open Theism. How one wishes to work out, in ones own mind, a reconciliation between God's sovereignty and man's free will, is up to us. However, an overemphasis of one over the other is not biblical. We must take a more balanced approach and avoid the extremes.
Pray: "Heavenly Father, we know you are sovereign and know all things. However, we also know that we have the ability to make choices. Help us to make good ones."
