Romans 6:22-2322 But now that you have been set free from sin and have become slaves of God, the benefit you reap leads to holiness, and the result is eternal life. 23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. NIV Bible Gateway.com
The moment we trust Jesus Christ as Lord and Savior, we enter into a life of faith. In other words, we live be assurance that God is all He claims to be and will do everything He promises. Salvation is instantaneous, but it takes a lifetime to learn and understand what that entails.
As soon as we are saved, God begins what is known as sanctification, teaching us to be like Him. This is a process, as it takes time to learn to walk by faith, trusting what we cannot see.
Even with God's Holy Spirit living inside of us, we nonetheless battle our flesh. We desire to do what God says and to see He sees, but because we have behavior patterns left over from our old sinful nature, we will falter and do things in our own strength, according to our own rationale. We must choose daily to follow His way.
To grow in godliness, we must learn to listen to our Father. But since this is not a natural tendency, self-discipline is needed. It is best to set a specific time each day to meditate upon God's Word. Eagerly expect Jesus to speak to you, and listen to what He is saying. Write notes in your Bible with the date and what the Lord has impressed upon you. Then, apply the truth you learn, and observe the results.
Hearing God's voice and being in tune with His Spirit are vital parts of walking in faith. But these things don't just happen; they require determined persistence. As with physical exercise, the more we strengthen our spiritual "muscles," the more the process becomes part of who we are.
