II Tim. 2:19 But God’s truth stands firm like a foundation stone with this inscription: “The Lord knows those who are his’ and “Those who claim they belong to the Lord must turn away from all wickedness.”
There is no foundation worthy of building our lives upon other than God’s truth. A life built on any other foundation is weak and will crumble in the midst of the storms of life. It is imperative for a healthy walk with God to stay grounded in the truth of God’s Word.
The Lord knows who are His and who aren’t. We are easily fooled by the appearance of others. We cannot see the heart of man and so we must be very careful when we make judgments about their hearts. We can even fool ourselves about ourselves. Just because we live like a child of God, believe the Bible to be true, pray and go to church doesn’t mean we are children of God. These things are important and should characterize a believer’s life, but they do not make us a child of God. A child of God is one who sincerely confesses his sin before Christ, asks Him for forgiveness and then lives like it. No one will make it to heaven by bypassing the cross.
Those who are truly children of God will turn away from all wickedness. There will be an obvious changing of lifestyles, both publicly and privately. There will be conscious choices made daily to turn away from sin. There will be a desire to not sin. There will be consistency in the way he does what is right before God and shuns what is evil. There will be consistency in his desire to grow in the grace and knowledge of Christ.
A child of God MUST turn away from all wickedness. He is compelled to do so because the Spirit is at work in him to make him holy. You cannot be a child of God and live in fellowship with Satan. You will hate sin and be determined to be a victor over it instead of a victim of it.
