Everyone wants to not only feel confident but actually be confident on the inside and on the outside. You will soar in life if you have confidence. How does one live a life of confidence? People are drawn to a confident person.
Isaiah 32:17 And the work of righteousness will be peace, And the service of righteousness, quietness and confidence forever.
When you became a Christian and surrendered your life to the Lordship of Christ, He gave you His righteousness which gave you the confidence to go before God.
Ephesians 3:12 In him and through faith in him we may approach God with freedom and confidence.
He gave us His righteousness that we might live according to His righteousness. Righteousness is doing life right or in other words, doing life according to His way. He tells us to clothe ourselves in righteousness. He wants us to put aside our old self and the old way of doing life and put on the new self and His way of doing life.
Romans 5:17 For if by the transgression of the one, death reigned through the one, much more those who receive the abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.
Grace is not the license to do what we want but the freedom and power to do life the right way. That is why the Lord says that when sin abounds then grace abounds. He still gives you the grace to do what is right after you have messed us. As Christians we are not sinless but we should sin less. When we do sin we need to make it right, or in other words we need to do righteousness according to God’s ways. If you owe someone money then pay them. Then you will have confidence when you see them and not want to shrink away in shame. If you need to ask forgiveness then do it so that you will have a clear conscience with that person.
Proverbs 3:26 For the Lord will be your confidence, And will keep your foot from being caught.
When He is your confidence you will not be afraid.
II Corinthians 3:4,5 Such confidence we have through Christ toward God. Not that we are adequate in ourselves to consider anything as coming from ourselves, but our adequacy is from God,
He is enough. When you experience this then you will want to trust Him more. If you are struggling with confidence in life about something in particular then do a word study in the Bible on that topic and then do exactly what the Bible says to do. He will help you and wants to prove His Word to you, that He is trustworthy.
Matthew 5:6 Blessed are those who hunger and thirst for righteousness, for they shall be satisfied.
