Because We Have A New-Life In-Christ

 Because We Have A New-Life In-Christ and have been made a new creature through faith in Him, we have been given all we need for life and godliness, and Peter is reminding us that we have a responsibility to live our lives in a way that honors the Lord. We are to maintain a heart that is cleansed and free from defilement. We are to preserve a state of moral purity. We are to remember that at the point of our salvation we were declared righteous in God's eyes through faith, and have a duty to continue in holiness of heart, by standing on the truth of the gospel and allowing our conduct to reflect the character of Christ, through the power of the Holy Spirit.
 We cannot purify our own heart. We cannot manufacture a sincere love for the brethren. We are unable to fervently love one another in our own strength. He purified our soul at the point of salvation and continues to purify it day by day, as we confess our sins, keep ourselves in fellowship with Him, and obey the truth of His Word. Godly conduct only comes from a godly character, and a godly character only comes from Christ; as we remain in Him and He in us.
 As we continue to purify our heart and soul through living a life of faith in obedience to Christ's commands, He will pour into our heart that sincere love for the brethren that only comes through faith in Him; we can only fervently love one another from the heart as the love of Christ streams into our soul and out to others.
1 Peter 1:22
Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart.

Our United Prayer:
Heavenly Father, thank You that in obedience to Your Word of truth we  believe in the Lord Jesus Christ for the forgiveness of sin, and have had our sin-sick souls cleansed by His blood and purified, through faith in Him. We pray that we would develop a sincere love for all our brothers and sisters in Christ. Give us  Christlike love, we pray. Develop in us  sacrificial love, so that we may fervently love others from the heart. We pray that we would grow in grace and in a knowledge of the Lord Jesus, and that He would increase and we would decrease until it is not we that live, but Christ that lives in us, and His love that flows through us. This we Pray in Jesus' name, AMEN.
