There are those who say Almighty God can grant you salvation through His Son, but that you have the power to throw it back in His face, when you want to go live in the pig wallow. THAT DOES NOT FIT SCRIPTURE either way you look at it. Let God be true and every man a liar.
Once saved, always saved, does NOT mean you think you can go out and live like the devil. Anyone who thinks that way had better seriously check out their relationship with the Savior. One does NOT receive Him just because you said a prayer. One has to be touched by the Holy Spirit and you will have a contrite and broken heart. You will long to be His and seek His face. You may be so broken you cannot form a prayer on your lips. But God will see your heart and your tears of repentance and your desire to be His.
NOW…there are those who say they belong to our God, but like hogs to the wallow they will return. The Scripture says they are swine and never truly belonged.
The Father made a covenant with us to abide with us…in Christ. God cannot lie and does not break His promises like a man can do.
If we are His, and we fall back into the ways of the flesh, He will deal with us as children. We are His children and He will disciple us, direct us and deal with us, as He sees fit. Earthly fathers discipline their children, so much more does our Heavenly Father. Our earthly fathers may discipline according to the flesh, but our Heavenly Father sees our hearts, knows our minds and how to guide us.
Check your heart. Is it beating? Is it beating for Christ or is it beating to fulfill your fleshly desires? Where will you spend eternity? Have you truly sought His face? There is a veil of darkness all around, but you can walk in the light up the path right into eternity with Him.
