Is there a reason you believe "getting into Heaven" is the point of being a Christian?
I guess for me that seems almost backwards. Salvation =/= going to Heaven, but rather salvation is God coming down to rescue us, which is an act of unmerited and unconditional grace. This He has done by the Incarnation, the Son and Word united Himself to our humanity, and by death and resurrection redeemed it. "Heaven" is simply "where" God is, and if Christ has reconciled us to God then we are with God, and ultimately that means when Christ returns to renew and restore creation, that means a resurrected life here forever on planet Earth with God.
However all that aside, the goal of the Christian life isn't "getting into Heaven"; rather it is God who has met us here in the Person of Christ, saving us, who then says, "I have saved you, I have forgiven you, now go and live" and upon which we now seek to live in the obedience of Christ, living in the shape of the Cross, not for our own salvation (which has been accomplished on Mt. Calvary once and for all), but to be bearers of God's Word--the Gospel of what God has accomplished by His Son--to the world, and in faith striving toward good works so that our neighbor might be fed, clothed, have drink, and be taken care of because this is the will of God.
The good works merit nothing, the life of living crucified is not earning us points with God, it does not bring us closer to God nor closer to "Heaven"; God has already become close to us by the Incarnation itself, and that's the Good News. Living crucified is out of fealty to our Lord, it is faithfulness to the Crucified Christ, who calls us to imitate Him in this world of suffering and evil. Not that we might gain what has already been freely given, but that we might live as Christ for the sake of our neighbor who suffers.
