2 Peter 1:5-8 5For this very reason, adding your diligence [to the divine promises], employ every effort in exercising your faith to develop virtue (excellence, resolution, Christian energy), and in [exercising] virtue [develop] knowledge (intelligence), 6And in [exercising] knowledge [develop] self-control, and in [exercising] self-control [develop] steadfastness (patience, endurance), and in [exercising] steadfastness [develop] godliness (piety), 7And in [exercising] godliness [develop] brotherly affection, and in [exercising] brotherly affection [develop] Christian love. 8For as these qualities are yours and increasingly abound in you, they will keep [you] from being idle or unfruitful unto the [full personal] knowledge of our Lord Jesus Christ (the Messiah, the Anointed One).
Exercising our faith develops virtue in our lives. Virtue is the quality of being morally good or righteous. 2 Corinthians 5:7 tells us 7For we walk by faith [we regulate our lives and conduct ourselves by our conviction or belief respecting man’s relationship to God and divine things, with trust and holy fervor; thus we walk] not by sight or appearance. Walking by faith means that we live our lives according to what we believe with respect to our relationship with God. Throughout the New Testament the words faith and belief are used interchangeably. Therefore we see that faith is simply what we believe. When we believe the Word of God and live our lives according to those beliefs, it puts us in a place of righteousness, or right-standing with God. Look at Romans 3:21-22 21But now the righteousness of God has been revealed independently and altogether apart from the Law, although actually it is attested by the Law and the Prophets, 22Namely, the righteousness of God which comes by believing with personal trust and confident reliance on Jesus Christ (the Messiah). [And it is meant] for all who believe. For there is no distinction. Righteousness comes by believing. That position of being in right-standing with Him comes when we are walking in faith.
Hebrews 11:6 6But without faith it is impossible to please and be satisfactory to Him. For whoever would come near to God must [necessarily] believe that God exists and that He is the rewarder of those who earnestly and diligently seek Him [out]. When we exercise our faith we please the Lord. Is it really that easy? Yes! Sometimes we want to make our Christian walk so difficult. If we simply do what the Word says in every situation, regardless of what we see and regardless of what we think, we will see the results in our lives. No matter what you are facing, if you use the principles in the Word you will be able to withstand anything. Exercise your faith. Allow virtue to be developed in you. Remember what Jesus said in Mark 9:23 23And Jesus said, [You say to Me], If You can do anything? [Why,] all things can be (are possible) to him who believes!
