I John 3:1-3 See how very much our heavenly Father loves us, for he allows us to be called his children, and we really are! But the people who belong to this world don't know God, so they don't understand that we are his children. Yes, dear friends, we are already God's children, and we can't even imagine what we will be like when Christ returns. But we do know that when he comes we will be like him, for we will see him as he really is. And all who believe this will keep themselves pure, just as Christ is pure.
All who seek after God apart from Christ is of this world. The world does not know Christ and are in the dark as to who God really is and how to get to Him. History ought to teach us this very valuable lesson. Mankind has always acknowledged the existence of God, but their concept of God has been distorted and taken them on a lot of weird paths. Without a personal relationship with Christ, no one can grasp who God is and how He relates to us.
In Christ, we are children of God and as His children we are able to grasp who God is. We learn from Him how to relate to Him. We learn who we are and who we will become. We can't understand all that we will be when the Lord returns, but we know enough to want to be it. Who we become now is but a taste of who we will be when we are freed from all of sin's influences over us. We will be as Jesus is, pure in heart. We no longer will struggle with sin. We will always live right with God.
Don't underestimate who you are in Christ, you are God's child. Don't underestimate God's love for you. And, don't underestimate who you will become in Christ. We are heirs to the Kingdom of God. We will be where God is forever and ever. We are heirs to a life with no pain, sorrow, or sin. We will live in perfect peace with God and one another forever. We will live forever in the glory of God and behold Him in all His majestic splendor. Oh, that will be, glory for me!! Praise God from whom all blessings flow!!
Don't listen to what the world says about God. God has given us, His children, the truth about Him and the truth sets us free. You are a child of God, live like it.
